Answer:
Option B.
Step-by-step explanation:
In the given events lets find out the event that has a probability other than 1/2.
A. Flipping a coin gives result of head or tail, so the probability of the result of tails is 1/2.
B. Choosing a vowel from a bag of tiles that contains one of each letter of the alphabet, so the probability of choosing vowel is 5/26.
C. A cube that has numbered from 1 to 6, there are 3 even numbers and 3 odd numbers, so the probability of rolling even number is 3/6 or 1/2.
D. There is 26 red cards in a standard deck of 52 cards, so the probability of choosing red card is 26/52 or 1/2.
Therefore, events A, C and D gives result of 1/2 and B other than 1/2
So Option B is the correct answer.
