When flipping a coin, what is the probability of landing on heads?
P(heads) = ?
1/2
100
When flipping a coin, the probability of landing on tails is 1/2. How many times do you expect the coin land on tails if the coin is flipped 18 times?
Expected value = probability x # of events
Expected value = 1/2 x 18 = 9 times

The table shows the results of 30 rolls of a six sided die. What is the experimental probability of rolling a 5? P(5) = ?
Experimental probability = # of events / # of trials
P(5) = 6/30 = 1/5

What are the values of the outliers?
70 and 80 years

On a six sided die, what is the probability of rolling a 2?
P(2) = ?
1/6
200
When rolling a six sided die, the probability of landing on a four is 1/6. How many times do you expect the die to land on four if the die is rolled 30 times?
Expected value = probability x # of events
Expected value = 1/6 x 30 = 5 times
200
The table shows the results of 30 rolls of a six sided die. What is the experimental probability of rolling a 1 or a 2? P(1 or 2)=?
Experimental probability = # of events / # of trials
P(1 or 2) = (6+6)/30 = 12/30 = 2/5

A class of 6th graders was asked how many Funko Pops they own. The following is the data.
0, 2, 5, 8, 8, 8, 9, 9, 10, 10, 10, 11, 12, 12, 12, 14, 15, 20, and 25
If lower fence = 2 and upper fence = 18, which values are outliers?
outliers = 0, 20, and 25

On a six sided die, what is the probability of rolling an even number?
P(even) = ?
3/6 = 1/2

A coin is flipped 44 times. How many times do you expect the coin to land on tails?
P(tails) = 1/2
Expected Value = probability x # of events
Expected Value = 1/2 x 44 = 22 times
300
What is the experimental probability that a randomly picked person will have 2 pets? P(2)=?
Experimental probability = # of events / # of trials
P(2) = 7/19

If the IQR = 14 and Q1 = 55, what is the Lower Fence?
Lower Fence = Q1 - 1.5IQR
Lower Fence = Q1 - 1.5IQR
Lower Fence = 55 - 1.5(14)
Lower Fence = 55 - 21 = 34

A spinner has an equal chance of landing on the numbers 1 through 8. What is the probability of spinning a number greater than 3?
P(greater than 3) = ?
5/8
400
When rolling a six sided die, how many times do you expect the die to land on a number less than 4 if the die is rolled 24 times?
P(less than 4) = 3/6 = 1/2
Expected Value = probability x # of events
Expected Value = 1/2 x 24 = 12 times
400
P(more than 7)=?
Experimental probability = # of events / # of trials
P(more than 7) = (7+7+1)/20 = 15/20 = 3/4

What do you call a pile of cats?
A meow-ntain
500
What is the Upper Fence?
IQR = Q3 - Q1 = 70 - 30 = 40
Upper Fence =Q3 + 1.5IQR
Upper Fence = 70 + 1.5(40)
Upper Fence = 70 + 60 = 130

A bag contains 3 red chips, 2 blue chips and 5 green chips. One chip is chosen at random.
P(blue or green) = ?
7/10
500
A spinner has an equal chance of landing on the numbers 1 through 8. If spun 48 times, how many times do you expect the spinner to land on a number greater than 3?
P(greater than 3) = 5/8
Expected value = probability x # of events
Expected value = 5/8 x 48 = 30 times
500
P(odd) = ?
Experimental probability = # of events / # of trials
P(odd) = (2+2+1)/11 = 5/11
