Question

A six sided die and a standard nickel are tossed. What is the probability that the number of dots on the upper face of the die is a prime number and the nickel lands heads facing up?

Answer 1

Probability of head and prime = 1/4 or 0.25

Explanation:

Total number face in dice = 6

Face that is prime ( 2,3,5) = 3

Total number face in nickel = 2

Total number of head in nickel = 1

Probabilty of prime = 3/6

Probabilty of prime = 1/2

Probabilty of head = 1/2

Probability of head and prime

= 1/2 * 1/2

= 1/4

= 0.25
