what is the probability that either event a or event b will occur? start by finding the probability of event a. p(a) = \frac{?}{17}

what is the probability that either event a or event b will occur? start by finding the probability of event a. p(a) = \frac{?}{17}

Answer

Explanation:

Step1: Identify probability components of A

The probability of event A is composed of the part within A only and the overlapping part (not shown to be non - zero here). Since the value within circle A is $\frac{9}{17}$ and there is no indication of an overlap affecting it, $P(A)$ is the value within circle A. $P(A)=\frac{9 + 6}{17}$

Step2: Calculate P(A)

$P(A)=\frac{15}{17}$

Answer:

$\frac{15}{17}$
