A) \[\frac{144}{625}\]
B) \[\frac{72}{3125}\]
C) \[\frac{216}{625}\]
D) None of these
Correct Answer: A
Solution :
Probability of success \[(p)=\frac{3}{5}\Rightarrow q=1-p=\frac{2}{5}\] Hence the probability of 2 hits in 5 attempts \[={}^{5}{{C}_{2}}{{\left( \frac{3}{5} \right)}^{2}}{{\left( \frac{2}{5} \right)}^{3}}=\frac{144}{625}.\]You need to login to perform this action.
