Question

next, find the probability of event b. p(b) = ?/19

Explanation:

Step1: Identify parts of event B

The parts of event B are the intersection part $\frac{10}{19}$ and the non - intersection part $\frac{2}{19}$.

Step2: Calculate probability of B

We add these two fractions: $P(B)=\frac{10}{19}+\frac{2}{19}$.
$P(B)=\frac{10 + 2}{19}=\frac{12}{19}$

Answer:

$\frac{12}{19}$
