Question

*HELP PLEASE*

Answer 1

If two events are disjoint (i.e. mutually exclusive) they cannot both occur and so we can determine probabilties by simple addition:

$P(AorB)=P(A)+P(B)$ 
$P(AorB)=\frac{40}{61}+\frac{2}{61}$ 
$P(AorB)=\frac{42}{61}$ 
$P(AorB)\approx 68.8\%$ 

A more complete answer would use a joint probability table but that's difficult to type out/format correctly here.
