We will flip a balanced coin 3 times and for each toss, record whether we get a Head or a Tail. Write all possible outcomes of this experiment to find the probability that we get exactly 2 heads.
Group of answer choices:
a. 1/8
b. 1/3
c. 3/8
d. 2/3

c. 3/8

Step-by-step explanation:

For each toss, there is a 50/50 probability that it lands on heads or tails. Let T be a tails and H be a heads, the sample space of this experiment is:

S={HHH, HHT ,HTT ,HTH, TTT, TTH, THH, THT}

The experiment has 8 possible outcomes. Only three of those outcomes have exaclty two heads (HHT, HTH, THH). Therefore, the probability of getting exactly two heads is 3/8.
