B) $ ^{10}C_4{{( \frac{1}{2} )}^{6}} $
C) $ ^{10}C_4{{( \frac{1}{2} )}^{8}} $
D) $ ^{10}C_6{{( \frac{1}{2} )}^{10}} $
Show Answer
Answer:
Correct Answer: D
Solution:
Required probability $ ={}^{10}C_4{{( \frac{1}{2} )}^{4}}{{( \frac{1}{2} )}^{6}}={}^{10}C_4{{( \frac{1}{2} )}^{10}} $
$ ={}^{10}C_6{{( \frac{1}{2} )}^{10}}. $
