Chapter 12, Problem AP4.2CPT

To determine

To find out what is P(A or B).

Answer to Problem AP4.2CPT

Option (c) is the correct option.

Explanation of Solution

It is given that,

  $\begin{array}{l}P(A)=0.24\\ P(B)=0.52\end{array}$

Thus, using the multiplication rule for independent events:

  $\begin{array}{l}P(\text{A and B)}=P(A)\times P(B)\\ =0.24\times 0.52\\ =0.1248\end{array}$

Now, we have that,

  $\begin{array}{l}P(\text{A or B)}=P(A)+P(B)-P(\text{A and B)}\\ =0.24+0.52-0.1248\\ =0.6352\end{array}$

Thus, option (c) is the correct option.
