Explanation: The probability of throwing at least two heads in three coin tosses is three in eight. The numerator is three because three specific outcomes match the event (getting exactly two heads), and the denominator is eight because there are eight possible outcomes in the sample set. Therefore, the probability is 3/8.

This is not correct because the question says "at least two heads":
HTH
HHT
THH

and!

HHH

The correct answer should be 1/2
