Question

A fair coin is tossed until either a tail occurs or a total of 4 tosses have been made. What is the probability that a tail occurs on the first toss?

1) 1/2
2) 1/4
3) 3/4
4) 1/8

Answer 1

The probability that a tail occurs on the first toss is 1/2 or Option 1) 1/2.

Step-by-step explanation:

To find the probability that a tail occurs on the first toss, we need to consider the possible outcomes. Since the coin is fair, there are two equally likely outcomes - heads (H) and tails (T). The probability of getting a tail on the first toss is 1/2 or Option 1) 1/2.
