Question

If you flip a coin 10 times, what are the odds that you will get the same number of heads and tails? ?

Answer 1

This is Binomial with n = 10 and p = 0.5 (assuming a fair coin)

Explanation:

Out of 10 flips, the probability of getting 5 heads (or tails) is ...

`P(X=5) = (10!)/(5!xx5!)xx(1/2)^5(1/2)^5=63/256~~0.246`

hope that helped
