The probability that an archer can hit a target is 3/4. He tries 4 times. The probability that he will hit the target at least 2 times is?

Since the probability that an archer can hit a target =3/4

Thus the probability that he can not hit a target =1/3

the required probability that he will hit the target at least 2 times is

=4C2 (?)² (?)²  +4C3 (3/4)³ (?) +4C4(3/4)⁴ (?)⁰

=(2/27)+(9/32)+(81/256)

=0.671
