A man tosses a coin 10 times, scoring 1 point for each head and 2 points for each tail. Let P(K) be the probability of scoring at least K points. The largest value of K such that `P(K)gt1//2` is -

Text Solution

Verified by Experts

The correct Answer is:

A, B

`P(Yge10)=1`.
On observation the maximum value of k will be 15 whose probability is greater than `(1)/(2)`.
