Answer:

1. Denote X the number of heads turn out in the experiment. What is the the set of possible values

of the variable X?

2. Suppose the coin is biased (i.e., loaded) so that the probability that a head turns out in a flip is

0.6. What are the mean and 4. A surgery has a success rate of 75%. Suppose that the surgery is performed on three

patients.

a. What is the probability that the surgery is successful on exactly 2 patients?

The number of successful surgeries, X can be represented by a binomial distribution

with n = 3 trials, success probability p = 0.75 and failure probability q = 1 − p = 0.25.

Therefore,

P(2) =n C2p

2

q

n−2 =3 C2(0.75)2

(0.25)1 ≈ 0.422.

b. Let X be the number of successes. What are the possible values of X? 0, 1, 2, 3

c. Create a probability distribution for X.

We must find P(0), P(1), P(2), and P(3). (We already have P(2)).the standard deviation of X?

3.What is the probability that the head turns out at least twice?

4. What is the probability that an odd number of heads turn out in 3 flips?
