Probablity of finding A or B or both A and B In a jungle, the probability of an animal being a mammal is 0.6, a nocturnal is 0.2. What is the probability that an animal found in this jungle is either a mammal, or nocturnal or both. Assume that these are independent traits.

**Hint:** The probability that $A$, $B$, or both $A$ and $B$ occur is $$ P(A\text{ and }B)+P(A\text{ and not }B)+P((\text{not }A)\text{ and }B). $$
