What is the probability of rolling an even number or flipping a tail?


Enter your answer as a reduced fraction, like this: 3/14

Answer 1

Both are 1/2

Explanation:

Count just the tails, that's the numerator

Count all the heads and tails, that's the denominator.

And for the 2nd fraction:

Count just the evens, that's the numerator

Count all the even and odd numbers, that's the denominator.

Answer 2

Answer: The answer to this question is 3/4

Explanation:

In this problem, there are 12 outcomes. Of those, 3 result in an even number and a tail, 3 more in an even number but not tail and 3 in a tail but an odd number, hence there are 9 desired outcomes.

Hence, the probability is given by: p=9/12=3/4
