Question

Find the probability of the indicated event if $P\left(A\right)=0.25andP\left(B\right)=0.45$

$P(A\cup B)$if A and B are mutually exclusive.

Short answer

The probability is$0.70$

Step-by-step solution

Step 1. Given Information 

The given data is$P\left(A\right)=0.25,P\left(B\right)=0.45$

Step 2. Calculation  

Substitute the given values in the formula to find the required value,

$$\begin{gathered} P(A\cup B)=P\left(A\right)+P\left(B\right) \\ =0.25+0.45 \\ =0.7 \end{gathered}$$
