A coin is loaded in such way that a tail is three times as likely to occur as a head. If the coin is flipped twice. Find the probability that two heads occur

Answer 1

From your data, with four tosses, you would get 3 tails and one head by chance.

The probability of one head would then be 1/4.

If the events are independent, the probability of both/all events occurring is determined by multiplying the probabilities of the individual events.
