sruthi  (7 years ago)

Probability of hitting the target= 1- probability of not hitting the target
if he hits once every 3 balls,
probability of hitting = 1/3, probability of not hitting=2/3
probability of not hitting the target all three times= (2/3)* (2/3)* (2/3)
probability of hitting target = 1 -(2/3)^3
19/7 so option B

hit the target=1-probability of not hitting the target
=1-p(0)
=1-3c0*(1/3)^0*(2/3)^3
=1-8/27
=19/27
