Suppose you roll a standard number cube and spin a spinner with four equal-sized sections labeled 1, 2, 3, 4. What is the probability you will roll a prime number and spin a prime number?

A. 1/4

B. 1/2

C. 1

D. 3/4

A; 1/4

Step-by-step explanation:

In a standard normal cube, we have the numbers labeled 1 to 6

the prime numbers we have here are 2, 3 and 5

The probability of selecting a prime number is thus 3/6 = 1/2

Now this means the probability of rolling a prime number here is 1/2

Now we calculate the probability of spinning a prime number

Prime numbers here are just 2 and 3

The probability of spinning a prime number is thus 2/4 = 1/2

Thus, the probability of rolling a prime number and spinning a prime number also becomes; 1/2 * 1/2 = 1/4
