An experiment consists of tossing a coin and then throwing it second time if a head occurs. If a tail occurs on the first toss, then a die is rolled once. Find the sample space.

An experiment consists of rolling a die and then tossing a coin once, if the number on the die is even. If the number on the die is odd the coin is tossed twice. Write the sample space for this experiment.

Three coins are tossed simultaneously. Find the sample space.

A coin is tossed twice. If the second toss results in a head, then a die is rolled. Write the sample space of the experiment.

In a toss of two coins, find the probability of getting both heads or both tails.

A pair of coins is tossed once. Find the probability of showing at least one head is :

Consider the experiment of tossing a coin. If the coin shows head, toss it again but if it shows tail, then throw a die. Find the conditional probability of the event that the die shows a number greater than 4, given that there is at least one tail.

A coin is tossed once, what is the probability that one head occurs?

A coin is tossed until a head appears or until it has been tossed three times. Given that 'head' does not occur on the first toss, what is the probability that the coin is tossed thrice?
