Question

Stacy performed an experiment in which she flipped a coin three times. The list below shows all the possible combinations of the outcome of the experiment.

HHH, HHT, HTH, HTT, THH, THT, TTH, TTT

Is Stacy more likely to flip a heads on the first try or flip a tails on the second two tries of the experiment?

A. Stacy is more likely to flip a tails on the second two tries of the experiment, because 4/8 > 2/8

B. Stacy is more likely to flip a heads on the first try of the experiment, because 6/8 > 4/8

C. Stacy is more likely to flip a tails on the second two tries of the experiment, because 6/8 > 4/8

D. Stacy is more likely to flip a heads on the first try of the experiment, because 6/8 > 4/8

Answer 1

option A is the correct answer.

Explanation:

Stacy is more likely to flip a tails on the second two tries of the experiment, because there are four possible outcomes with tails on the second two tries (HT, TT, HT, TT) out of a total of eight possible outcomes, which gives a probability of 4/8 or 1/2. On the other hand, there are only three possible outcomes with heads on the first try (H**, T**, H, T) out of a total of eight possible outcomes, which gives a probability of 3/8. Therefore, option A is the correct answer.
