Question

You spin a spinner with 5 equal sections numbered 1-5 and then toss a standard number cube. what is the probability of landing on a 4 on the spinner and tossing a prime number on the number cube?

A. 1/5
B. 1/2
C. 2/7
D. 1/10

Answer 1

Answer: D. 1/10

Explanation:

With there being 5 sections on the spinner and only one number wanted to be spun, the probability of that would be 1/5.

On a dice, 3 of the numbers on a cube are prime (1, 3 and 5). So the probability would be 3/6 or 1/2.

1/5 x 1/2 = 1/10, so the probability of spinning a 4 and rolling a prime number would be 1/10, or 10%
