Find the probability distribution of the number of successes in two tosses of a die, where a success is defined as
(i) number greater than 4
(ii) six appears on at least one die

Find the probability distribution of (i) number of heads in two tosses of a coin.  (ii) number of tails in the simultaneous tosses of three coins. (iii) number of heads in four tosses of a coin.

Find the probability distribution of the maximum of the two scores obtained when a die is thrown twice. Determine also the mean of the distribution.

Find the probability of receiving a prime number in the experiment of throwing a balanced die once.

A die is tossed. The probability that the number on a die is divisible by 3 is …….

A dice is tossed twice. Find probability of getting a number greater than 3 on each toss.

Two unbiased dice are thrown. The probability that the sum of the numbers appearing on the top face of two dice is greater than 7, if 4 appear on the top face of first dice is ………..

A die is thrown, find the probability of following events : A number greater than or equal to 3 will appear.

In a binomial distribution B(n , p=1/4) , if the probability of at least one success is greater than or equal to 9/(10) , then n is greater than

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 die is thrown twice and the sum of the numbers appearing is observed to be 6. What is the conditional probability that the number 4 has appeared at least once?
