A man can hit a target once in 3 shots.If he fires 3 shots in succession, find the probability that he will hit his target.
A) 2/9
b)19/27
C)5/9
d)1/27
Read Solution (Total 9)
-
- 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 - 8 years agoHelpfull: Yes(34) No(5)
- 1/3 + 2/3 * 1/3 + 2/3 * 2/3 * 1/3=19/27

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

- 8 years agoHelpfull: Yes(1) No(6)
- Ans= 1 - (2/3)^3 = (27-8)/27 = 19/27
- 8 years agoHelpfull: Yes(1) No(1)
- 1-(2*3)^3=1-8/27
(27-8)/27=19/27 - 7 years agoHelpfull: Yes(1) No(0)
- Ans. 19/27.
