I am not sure of the ans but i am trying
then ans may be 10C3 / 210.
If u got the correct ans pls post it
thank u

Your answer is correct but a more general method is
Probability of sucess = 1/2
Probability of failure = 1/2
The probability of m successes in n trials where a is the probability of success and b is probability of failure is nCm am bn-m
So it is 3C10 (0.5)10
What is the probability of getting head 5 heads in 10 trails of an unfair coin for which the probability of getting head in a single trail is 0.75?
I have added the above to Proability e Book @

One more probability question
P is product of three natural numbers. What is the probability that P is divisible by 10? a. 0.451
b. 0.271
c. 0.4874
d. 0.427
prob of head(success)=3/4 prob of tail(failure)=1/4 becoz prob of head+prob of tail=1 now we want 5 heads out of 10 trails therefore: prob=(10C5)((3/4)^5)(1/4)^5)
can anyone tell me hw to solve the question on the product of three nos
ans is 10c3*(0.5)*(0.5)^9
