Answer 2

Calculating the Probability of Choosing a Non-Doll Toy

To calculate the probability of choosing a non-doll toy from the 20 different toys available, we can use the following formula:

Probability (P) = Number of favorable outcomes / Total number of outcomes

In this case, the number of favorable outcomes is the number of non-doll toys, and the total number of outcomes is the total number of toys.

Calculation

Given that there are 20 different toys and 4 of them are dolls, the number of non-doll toys is 20 - 4 = 16.

Therefore, the probability of choosing a non-doll toy is:

P = 16 / 20 = 0.8

So, the probability of choosing a non-doll toy is 0.8.
