which of the following best shows the relationship between the probability of an event, a, and its complement, a^c?\n a. p(a) < p(a^c)\n b. p(a) = p(a^c)\n c. p(a) = 1 - p(a^c)\n d. p(a) > p(a^c)
Answer
Explanation:
Step1: Recall probability - complement rule
The sum of the probability of an event and its complement is 1. That is, $P(A)+P(A^{C}) = 1$.
Step2: Rearrange the formula
By subtracting $P(A^{C})$ from both sides of the equation $P(A)+P(A^{C}) = 1$, we get $P(A)=1 - P(A^{C})$.
Answer:
C. $P(A)=1 - P(A^{C})$
