Question

The faces of a cube are numbered 1-6. if the cube is tossed once what is the probability that a prime number or a number divisible by 2 is obtained

Answer 1

Prime Numbers 2, 3, 5

Divisible by 2 - 2, 4, 6

One is NOT a prime number.

So, there are 5 out of 6 numbers that are even or are prime.

This leaves only 1 number that isn't.

So, the probability is 5/6 that the number rolled will be prime or even.
