Answer:

0.005371

Step-by-step explanation:

Given that a fair coin is tossed 11 times.

Since coin is fair probability for head p = 0.5 and q = prob for tail =0.5

Each trial is independent of the other. Hence X no of heads is binomial with n = 11 and p =0.5

Prob for getting 10 heads out of 11 tosses

=P(X=10)

=11C10 (0.5)^{10} (0.5)\\= 0.005371
