Suppose a coin with Pr[H]=4/5Pr[H]=4/5 is flipped 4 times. Answer the following questions:

1. What is the probability exactly 2 heads were flipped?

2. What is the probability that heads then tails then heads then tails was flipped?

Step 1

Given Pr(H)= 4/5

Number of trials = 4

X= number of times head comes

Each trial is independent so, it is Bernoulli trial.

1)

We have to find P(X=2)
