a) There are 7 shots in a team. Each of them hits some target with probability
0.3. They shoot simultaneously and independently of each other. Find the probability
that at least one of them will hit the target.
b) Find the probability that the target will be hit at least once if the team includes
8 shots.
c) Suppose the probability of hitting the target by a team (at least once) has to
be not less than 0.97. Each shot hits the target with probability 0.3. How big has to
be the team to ful¯ll this condition?
