(a)
Binomial probability
(b)
the probability that success occurs exactly $r$ times is:
$$P(r \text { successes in } n \text { trials })=C(n, r) p^{r}(1-p)^{n-r}$$
(c)
the probability that she hits the target exactly 3 times in 5 attempts will be:
$$P(3 \text { hits in } 5 \text { tries })=C(5,3)(0.6)^{3}(0.4)^{2}=0.3456$$
