we are asked to determine the probability of one or another event happening. This can be calculated with "Or" rule for probability, that is:
[tex]P(\text{AorB)}=P(A)+P(B)-P(\text{AandB)}[/tex]Replacing for AA and PM probabilities we get:
[tex]P(\text{ AAorPM)=P(AA)+P(PM)}[/tex]Replacing the probabilities:
[tex]P(\text{ AAorPM)=}0.39+0.26-0.05[/tex]Solving the operations:
[tex]P(\text{ AAorPM)=}0.6[/tex]Therefore, the probability is 0.6.
