Using a six-sided die, what is the probability of rolling either a 5 or a 6?
A)1/6 × 1/6 = 1/36
B)1/6 + 1/6 = 1/3
C)1/6 + 1/6 = 2/3
D)1/6

Question

Quizplus · Accepted Answer

There are 6 possible outcomes when rolling a six-sided die, and only 2 of them (5 and 6) satisfy the condition of rolling either a 5 or a 6. Therefore, the probability is the sum of the probabilities of rolling a 5 or a 6, which is 1/6 + 1/6 = 1/3. Option A represents the probability of rolling a 5 and a 6 consecutively. Option C is incorrect as probabilities cannot be greater than 1. Option D represents the probability of rolling either a specific number, which is not what the question asked for.
