Question #d4ff9

1 Answer

P(x=0)=0.09

Explanation:

He has to miss in all the three attempts.

1st attempt
Probability of hitting the target : P1=0.7
Probability of not hitting the target : p1=10.7=0.3

2nd attempt
Probability of hitting the target : P2=0.5
Probability of not hitting the target : p2=10.5=0.5

3rd attempt
Probability of hitting the target : P3=0.4
Probability of not hitting the target: p3=10.4=0.6

It is a compound event

P(x=0)=p1×p2×p3=0.3×0.5×0.6=0.09
