Question

what is the probability that either event a or event b will occur? start by finding the probability of event a. p(a) = \frac{?}{19}

Explanation:

Step1: Identify parts of event A

The probability of event A is the sum of the probabilities in the regions that make up A.
$P(A)=\frac{3}{19}+\frac{10}{19}$

Step2: Calculate P(A)

$P(A)=\frac{3 + 10}{19}=\frac{13}{19}$

Answer:

$\frac{13}{19}$
