QUESTION
When you roll a fair die, what is the probability of getting:
a.) a five
b.) an even number
c.) a four or a five
ANSWER
a.) The probability of rolling a five on a fair die is 1/6. This is because there is only one favorable outcome (rolling a five) out of the six possible outcomes (rolling a 1, 2, 3, 4, 5, or 6).
b.) The probability of rolling an even number on a fair die is 1/2. This is because there are three favorable outcomes (rolling a 2, 4, or 6) out of the six possible outcomes. Wherein, 3/6 in lowest terms is 1/2.
c.) The probability of rolling a four or a five on a fair die is 1/3. This is because there are two favorable outcomes (rolling a 4 or a 5) out of the six possible outcomes. Wherein, 2/6 in lowest term is 1/3.
