what is the complement of it snowing 3 days out of the week? p = 4/7 p = 2/7 p = 5/7 p = 3/7
what is the complement of it snowing 3 days out of the week? p = 4/7 p = 2/7 p = 5/7 p = 3/7
Answer
Explanation:
Step1: Recall complement rule
The sum of an event's probability and its complement's probability is 1. A week has 7 days.
Step2: Calculate complement
If the event is snowing 3 days out of 7, then the complement is the number of non - snowing days out of 7. So (P'=1 - \frac{3}{7}=\frac{7 - 3}{7}=\frac{4}{7}).
Answer:
A. (P' = 4/7)
