Question

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 1 tail.
a. 2/3
b. 1/8
c. 1/3
d. 3/8

Answer 1

Answer: A- 2/3

Step-by-step explanation:

Possible outcomes when a coin is tossed 3 times is 1/2 + 1/2+ 1/2= 3/2

Probability of getting exactly one tail=

3/2x=1

x=1÷3/2

=1 ×2/3

=2/3
