how likely are you to not roll a 1 on a regular die? (complement) p = 2/6 p = 3/6 p = 5/6 p = 1/6
how likely are you to not roll a 1 on a regular die? (complement) p = 2/6 p = 3/6 p = 5/6 p = 1/6
Answer
Explanation:
Step1: Determine total outcomes
A regular die has 6 sides, so total outcomes $n = 6$.
Step2: Determine favorable outcomes
The event of rolling a 1 has 1 outcome. The event of not - rolling a 1 has $6 - 1=5$ outcomes.
Step3: Calculate probability
The probability formula is $P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$. So the probability of not rolling a 1, $P'=\frac{5}{6}$.
Answer:
C. $P' = 5/6$
