Question

Which event has a probability other than One-half?
flipping a coin with the result of tails
choosing a vowel from a bag of tiles that contains one of each letter of the alphabet
rolling an even number on a number cube that is numbered from 1 to 6
choosing a red card from a standard deck of cards (a standard deck has 52 cards 26 of which are red)

Answer 1

Choosing a vowel from the 26-letter alphabet. There are 5 vowels (A, E, I, O, U), so the probability is 5/26, which is not 1/2. The others each have probability 1/2.
