Answer:
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
