chapter 3.3.2 independence and mutually exclusive events review score: 6/15 answered: 6/14 question 7 in this problem, enter the answer as a simplified fraction. suppose we roll a die once. what is the probability that we roll a 5 or a 1?

Explanation:

Step1: Determine total outcomes

A die has 6 faces, so total outcomes $n(S)=6$.

Step2: Determine favorable outcomes

Rolling a 5 or a 1 gives 2 favorable outcomes, so $n(A) = 2$.

Step3: Calculate probability

The probability formula is $P(A)=\frac{n(A)}{n(S)}$, so $P=\frac{2}{6}=\frac{1}{3}$.

Answer:

$\frac{1}{3}$
