ANSWER

P(AuB) = 0.23

STEP-BY-STEP EXPLANATION:

Given information

P(A) = 0.2

P(B) = 0.1

P(AnB) = 0.07

What is P(AUB)

[tex]P(\text{AuB) = P(A) + P(B) }-\text{ P(AnB)}[/tex]

The next step is to substitute the above data into the formula

[tex]\begin{gathered} P(\text{AuB) = 0.2 + 0.1 - 0.07} \\ P(\text{AuB) = 0.3 - 0.07} \\ P(\text{AuB) = 0.23} \end{gathered}[/tex]
