A) 17
B) 1
C) 121
D) 137
Correct Answer: D
Solution :
\[np=8\] \[npq=4\] \[q=\frac{1}{2}\Rightarrow p=\frac{1}{2}\] \[n=16\] \[p(x=r){{=}^{16}}{{C}_{r}}{{\left( \frac{1}{2} \right)}^{16}}\] \[p(x\le 2)=\frac{^{16}{{C}_{0}}{{+}^{16}}{{C}_{1}}{{+}^{16}}{{C}_{2}}}{{{2}^{16}}}\]\[=\frac{137}{{{2}^{16}}}\]You need to login to perform this action.
