Probability of HIT Target = 1/4

Probability of Not HIT Target = 1- 1/4 = 3/4

so NOT hit in 4 target= $\frac{3}{4}\times \frac{3}{4}\times \frac{3}{4}\times \frac{3}{4} = \frac{81}{256}$

if hit at least one target then answer is 175/256?

if I'm right?

yes...

Answer 1

P(hit) = 1/4

P(not hit) = 1- 1/4 = 3/4

P(finall prob of not hit ) = 3/4*3/4*3/4 =81/256
