Question

The probability that a gun shot hitting a target is 1/3. If five gun shots aimed at the target. Find the probability that 2 shots miss the target.

Answer 1

Let x be the no. of shots hitting the target then 

n = 5, p = \(\frac{1}{3},\) 

∴ q =\(\frac{2}{3}\)

The p.m.f is

p(2 shots missing the target)

= p (x = 3 gum shots hit the target)
