Asked by Jary

A game consists of drawing a number from 1-20. A player wins if the number drawn is either a prime number or a perfect square. What is the probability of winning the game?
Answered by Reiny
from 1-20
number of primes is 8
number of perfect squares = 4
with no overlap

so prob(primes or perfect squares) = 12/20
= 3/5
