The conversation between human and AI assistant.
If you flip three fair coins, what is the probability that the first two flips will both be heads, and the third flip will be either heads or tails?
What if we want the probability of getting two heads in a row, followed by either heads or tails?
That would be the probability of getting HH followed by H or T, which is 1/4. The probability of getting HH on the first two flips is 1/4, and the probability of getting either H or T on the third flip is 1/2, so the overall probability is 1/4 * 1/2 = 1/8.
