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:

$P(AandB)=0.6\times0.45$

Solving the operations:

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

Therefore, the probability of A and B is 0.27.
