Question

to find probability, divide the number of _________ by the number of trials.
a members
b outcomes
what is the probability she got a black jelly bean?
a 1/4
b 1/3
c 1/2

Explanation:

The formula for probability is \(P=\frac{\text{number of favorable outcomes}}{\text{number of trials}}\). So for the first question, we need to divide the number of favorable outcomes by the number of trials.
For the second question, assume there are 4 jelly - beans in total and 1 is black (since the probability is given as a fraction). Using the formula \(P = \frac{\text{number of favorable outcomes}}{\text{number of trials}}\), if the number of favorable outcomes (black jelly - beans) is 1 and the number of trials (total jelly - beans) is 4, the probability is \(\frac{1}{4}\).

Answer:

1. B. outcomes
2. A. \(1/4\)
