Josh flipped this quarter 50 times. It landed on heads 22 times and it landed on tails 28 times. What was the experimental probability of flipping this quarter and having it land on tails?

• 22

• 28

• 28/50

• 14/25

Experimental probability is________________________

• the ratio of the number of times an event occurs to the total number of trials.

• the likelihood of an experiment being successful.

• the ratio of the number of favorable outcomes to the number of possible outcomes

• the likelihood of getting a favorable outcome.

The theoretical probability that you will choose a green marble from a bag is 3/7. There are 35 marbles in the bag. How many are green?

• 35

• 7

• 3

• 15

Theoretical Probability is

• the ratio of the number of favorable outcomes to the number of possible outcomes

• the likelihood that your theory is correct.

• the ratio of the number of favorable outcomes to the number of tries.

• the likelihood that an event might occur.
