A cup contains 6 purple marbles, 5 blue marbles, and 4 green marbles. THIS is the probability that Dana reached into the cup and picked a green marble if you know she did NOT pick a purple marble?
What is 4/9? What is .444444 (.44 "repeating")? What is (approximately) 44%?
100
The lion exhibit at Zoo Atlanta contains 5 lionesses and 3 lions. If lions begin to walk out of the den into sight--one at a time, then return back in before another lion walks out--THIS is the probability of seeing a lion, then a lioness, and then another lion.
What is 45/512? What is 0.08789... (0.09)? What is (approximately) 8.8% or 9%?

For two events A and B, it is known that P(A) = 0.20, P(B) = 0.40 and P(A ∪ B) = 0.50. If asked to find P(A ∩ B), you consider THIS type of probability.
What is Overlapping?
100
THIS means "intersecting" (shared outcomes/overlapping).
What is "∩"? (this can be stated/described or written/drawn)

Using this chart, THIS is the probability that a student did not take medicine but suffered a cold for 4-7. http://study.com/cimages/multimages/16/con2.jpg
What is 79/200? What is 0.395? What is 39.5%?

In your class, 56% of the students get an allowance and 41% of the students who get an allowance also do household chores. What is the probability that a student in your class does household chores given that the student gets an allowance?
What is .7321... (0.73)? What is (approximately) 73%?

Talia & Tari sometimes mix-match their socks. My sister never cares about matching her socks... Her sock drawer contains 3 red socks, 5 white socks, and 7 blue socks. Without looking, she takes out a sock and then takes out a second sock without returning the first one to the drawer. What is the probability that both socks are blue?
What is 42/210? What is 1/5? What is 0.2? What is 20%?
200
For two events A and B, it is known that P(A) = 0.20, P(B) = 0.40 and P(A ∪ B) = 0.50. Find P(A ∩ B).
What is P(A ∩ B) = 0.10?
200
THIS means "union" (all outcomes of each event combines).
What is "∪"? (this can be stated/described or written/drawn)
300
A box contains 7 green tiles, 2 white tiles, and 11 red tiles. Manuel will reach into the bag and select a tile without looking. THIS is the probability that he will select either a green tile or a white tile.
What is 9/20? What is 0.45? What is 45%?

Use the following table to calculate the probability that a randomly selected student had a cold for 1-3 days given that the student did take medicine. http://study.com/cimages/multimages/16/con2.jpg
What is 86/102? What is 0.843... (0.84)? What is (approximately) 84%?
300
A hat contains 15 red raffle tickets, 13 yellow raffle tickets, and 12 blue raffle tickets. Once a ticket is drawn, it is not replaced. THIS is the probability of drawing a red ticket on the first draw and a second red ticket on the next draw.
What is 210/1560? What is 7/52? What is 0.1346... (0.13)? What is (approximately) 13%?
300
For two events B and C, it is known that P(C|B) = 0.61 and P(C ∩ B) = 0.48. Find P(B). THIS is the type of probability, and THIS is the solution for P(B).
What is Dependent, and P(B) = 0.78688... (0.79)?
300
THIS means "probability of event b".
What is "P of B"? What is "P(B)"? (this can be stated/described or written/drawn)
400
THIS is the difference between the FORMULAS of mutually exclusive probability and overlapping probability.
What is mutually exclusive formula is P(A or B) = P(A) + P(B) & overlapping formula is P(A ∪ B) = P(A) + P(B) - P(A ∩ B)? (the formulas can be stated or written but must be exact)
400
THIS is the key word that lets you know the probability is conditional. It is the word you say when you reach the *bar* of the formula in "P(B|A)=...".
What is "given"?
400
THIS is the difference between Independent & Dependent Events/Probability.
What is with independent, whatever is taken out is replaced and with dependent, whatever is taken out is kept out? (any verbiage covering this concept accurately will be accepted)
400
Joel and Rico play basketball. The probability that Joel makes a 3 pointer is 64%. The probability that Rico makes a 3 pointer is 87.5%. The probability of at least one of them making a 3 pointer is 95.5%. THIS is the probability, as a percent, that both Joel and Rico will make a 3 pointer.
What is 56%?
400
THIS means "complementary" or "NOT this probability". MUST provide both options for credit.
What is ' or -? What is "apostrophe" or "bar"? (this can be stated/described or written/drawn)
500
THIS is the difference between the IDEA of mutually exclusive probability and overlapping probability.
What is mutually exclusive events happen separate of each other--cannot occur at the same time, & overlapping events have an area where they intersect or both happen at the same time--having at least one common outcome? (I will take any statements that cover this concept accurately)
500
THIS is the FORMULA for conditional probability.
What is P(B|A) = P(A ∩ B) / P(A)?
500
THIS is the formula for Independent & Dependent Probability.
What is Independent: P(A ∩ B) = P(A) x P(B); Dependent: P(A ∩ B) = P(A) x P(B|A)?
500
Suppose that the probability of Eirik coming to a party is 80% and the probability of Emma coming to a party is 95%. Assuming that these events are independent, THIS is the probability that they both will come to a party.
What is 7600/10000? What is 76/100? What is 76%

THIS is a visual aid often used to show the probabilities of two intersecting/overlapping events. (HINT: circles)
What is a Venn Diagram? (this can be stated/described or written/drawn)
