Theoretical
ONE DICE IS THROWN, WHAT IS THE PROBABILITY OF ROLLING A 3
1/6
A coin is flipped 100 times and the results were 25 heads and 75 tails. Based in the experiment what is the probability of flipping the coin and getting heads up?
1/4
Define "theoretical probability'. Is it based on calculation or experiment?
It is the calculated probability
How likely is it that a coin is flipped and lands on tails?
1/2
A carousel has 2 jumping horses and 2 standing horses. What is the probability of randomly selecting a jumping horse?
1/2, or 0.50, or 50%
A coin is tossed 1000 times resulting in 700 heads and 300 tails. What does this mean about the coin?
It is not fair
Define "experimental probability."
The probability of what actually occurs based on an experiment.
How likely is it that a number cube is tossed and lands on 3?
1/6
What is the probability of rolling two odd numbers in a row with a standard number cube?
1/4, or 0.25, or 25%
A letter tile is randomly selected from a bag, recorded, and replaced 16 times. The results are listed below. What is the experimental probability of selecting the letter "E"? A = 4, E = 5, I = 4, and O = 3
5/16
What is the sample space?
The total number of outcomes
How likely is it that a number cube is tossed and it lands on 8?
never going to happen
There are 3 red marbles, 2 green marbles. One marble is taken out and not replaced. A second marble is then taken out and not replaced. What is the probability that a red marble and then another red marble is chosen
3/10
Pedro recorded the types of birds that visit his bird feeder. Based on the results below, what is the probability the next bird will be a chickadee? Woodpecker = 3, Chickadee = 5, Cardinal = 1, Sparrow = 13, Blue Jay = 3; 25 total birds
3/25
Define "independent event."
When one event occurs and the item is replaced before the second event occurs.
How likely is it that a number cube is tossed and lands on any number 1-6?
100%
Jarvonya spins a spinner with 5 equal sections numbered 1-5 and she spins another spinner with 5 equal sections with the letters A-E. What is the probability she will spin a 4 and a B?
1/25 or 0.04, or 4%
A six-sided die is thrown 50 times. Using the list below, how does the theoretical probability of rolling a 3 compare to the experimental probability of rolling a 3? This is the list of the number rolled followed by the quantity 1:8, 2:6, 3:7, 4:12, 5:10, 6:7
The experimental probability is 7/50 =.84/6
The theoretical probability is 1/6
Define "dependent event."
When one event occurs and that item is not replaced before the second event occurs.
How likely is it that a number cube lands on 2 and a coin lands on heads?
1/12
