Question

Probability is a major part of genetics, and two very common rules are the Rule of Addition and the Rule of Multiplication. Using a six-sided die, what is the probability of rolling either a 5 or a 6? A. 1/6 + 1/6 = 1/12 B. 1/6 × 1/6 = 1/36 C. 1/6 + 1/6 = 1/3 D. 1/6 + 1/6 = 2/3

Answer 1

To find the probability of rolling either a 5 or a 6 with a six-sided die, you can use the Rule of Addition, which states that the probability of either of two mutually exclusive events occurring is the sum of their individual probabilities.

The die has six sides, and there is one 5 and one 6 among those sides. So, the probability of rolling either a 5 or a 6 is:

P(5 or 6) = P(5) + P(6) = 1/6 + 1/6 = 2/6 = 1/3

So, the correct answer is C. 1/6 + 1/6 = 1/3.
