I am struggling with this equation Statistics for QNT 275.

Consider the following test of whether a coin is fair.

Toss the coin five times. If the coin lands either all heads or all tails, reject Ho: p= 1/2.

(The p denotes the chance for the coin to land on heads.) Complete parts a and b.

(a) What is the probability of a Type I error for this procedure?

Answer: 1/16 ..... I was able to get this part

(b) If p = 3/8, what is the probability of a Type II error for this procedure?

Please show work so I have better understanding on how to solve this.

(Type an integer or a simplified fraction.)
