Question

P(A)=0.35P(B)=0.40P(A and B)=0.13Find P(A or B).Round your answer to two decimal places.

Answer 1

Given:

`\begin{gathered} P\left(A\right)=0.35 \\ P\left(B\right)=0.40 \\ P\left(A\text{ }and\text{ }B\right)=0.13 \end{gathered}`

To find:

`P(A\text{ or }B)`

Step-by-step explanation:

Using the formula,

`\begin{gathered} P(A\text{ or}B)=P(A)+P(B)-P(A\text{ and }B) \\ =0.35+0.40-0.13 \\ =0.62 \end{gathered}`

Therefore, the value is,

`P(A\text{ or }B)=0.62`

Final answer:

The value is,

`P(A\text{ or }B)=0.62`
