Question

A coin is tossed, and a standard number cube is rolled. What is the probability that the coin shows heads and the number cube shows an even number?

one-sixth
1
one-fourth
one-half

Answer 1

The total possibility that the head and even no on dice appears is 3. and total possible choice are 12 {head ->(1,2,3,4,5,6) & tail->(1,2,3,4,5,6)}. so the probability is 3/12= 1/4.?

Answer 2

That's one way to do it. Good job! Another way:

These are independent events so the total probability will be the product of the individual probabilities:

1/2 times 1/2 = 1/4

Answer 3

Thanks.
