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:

For the first question, the formula for probability is \( P=\frac{\text{number of favorable outcomes}}{\text{number of trials}}\). So the blank should be filled with “outcomes”.
For the second question, assume there are an equal number of black and non - black jelly beans (for example, if there are 2 black and 2 non - black, total \(n = 4\), favorable \(m=2\)), the probability \(P=\frac{2}{4}=\frac{1}{2}\).

Answer:

1. B. outcomes
2. C. \(1/2\)
