Answer to Question #175915 in Statistics and Probability for Roy Teodoro

Question

N=200, n=10

Answer 1

Here, N= 200

and, n= 10

Probability of head = $\dfrac{1}{2}$

So, $p= \dfrac{1}{2} \ \ q= \dfrac{1}{2}$

So, Probability of getting head = $^{200}C_{10}(\frac{1}{2})^{10}(\frac{1}{2})^{190}$
