If X follows the binomial distribution with parameters n=6 and p and 9p(X=4)=P(X=2), then p isA. `1//4`B. `1//3`C. `1//2`D. `2//3`

If X follows the binomial distribution with parameters n=6 and p and 9

1.	If X follows the binomial distribution with parameters n=6 and p and 9p(X=4)=P(X=2), then p isA. `1//4`B. `1//3`C. `1//2`D. `2//3`
Answer» Correct Answer - A Given, `9P(X=4)=P(X=2)` `therefore9*""^(6)C_(4)p^(4)(1-p)^(2)=""^(6)C_(2)p^(2)(1-p)^(4)` `implies((1-p)^(2))/(p^(2))=9` `implies(1-q)/(p)=3` `impliesp=1//4`
