Question

at the movie theater, janna and amy wait in different lines to buy one of 5 different snack options (popcorn, pretzel, nachos, chocolate, or cotton candy). assuming the girls are equally likely to buy any one of the options, what is the probability that janna will buy popcorn and amy will buy a pretzel? (1 point) 0.20 0.40 0.04 0.02

Explanation:

Step1: Calculate probability for Janna

Probability Janna buys popcorn: $\frac{1}{5}= 0.2$ (1 favorable outcome out of 5 options).

Step2: Calculate probability for Amy

Probability Amy buys pretzel: $\frac{1}{5}=0.2$ (1 favorable outcome out of 5 options).

Step3: Use multiplication rule for independent events

Since events are independent, $P(\text{Janna popcorn and Amy pretzel})=0.2\times0.2$

Answer:

$0.04$
