Question

A carnival has a duck pond booth. You choose a rubber duck at random. The mark on the bottom of the duck tells you whether you won a small, medium, or large prize, or no prize at all. There are 65 ducks floating in the pond. There are 3 marked as large-prize winners, 13 ducks marked as medium-prize winners, and 21 ducks marked as small-prize winners. Find the theoretical probability of winning a medium prize at the duck pond. Express your answer as a decimal. If necessary, round your answer to the nearest thousandth.

0.2
0.8
5
0.569

Answer 1

Take the number of medium ducks and divide it by the overall number of ducks
13/65=.2

Answer 2

Hi there! :)  I believe the answer is 0.2. The way I got 0.2 is because there are 13 medium-sized ducks and there are 65 total ducks floating I did 13/65( 13 divided by 65) which equals 0.2. For theoretical probability you divide by the number of outcomes.

Hoped I helped! :D
