Question

1) P(A) = 0.6 P(B) = 0.45 P(A and B) = ? O 0.35 0.65 O 0.75 O 0.27

Answer 1

We are given the following probabilities:

`\begin{gathered} P(A)=0.6 \\ P(B)=0.45 \end{gathered}`

We are to find P(A and B), to do that we will use the following relationship:

`P(\text{AandB)=P(A) x P(B)}`

Replacing we get:

`P(AandB)=0.6*0.45`

Solving the operations:

`P(\text{AandB)}=0.27`

Therefore, the probability of A and B is 0.27.
