Catherine used a dice and noted the number which appeared after throwing it. She repeated the exercise 40 times and noted the number every time as shown ahead.

A girl throws a die. If she gets 5 or 6, tosses a coin three times and notes the number of heads. If she gets 1,2,3 or 4, she tosses a coin two times and notes the number of heads. If she obtained exactly two heads, what is the probability that she throws 1,2,3 or 4 with the die.

A die is thrown twice. Each time the number appearing on it is recorded. Describe the events : A : both numbers are odd B : both numbers are even C : sum of numbers is less than 6. Which pairs of events are mutually exclusive ?

A bag contains 2 white and 1 red ball. One ball is drawn at random and then put back in the bag after noting its colour. The process is repeated again. If 'X' denotes the number of red balls recorded in the two draws, describe 'X'.

Suppose a girl throws a die. If she gets a 5 or 6, she tosses a coin three times and notes the numbers of heads. If she gets 1,2,3, or 4, she tosses a coin once and notes whether a head or a tail is obtained. If she attained exactly one head what is the probability that she threw 1,2,3, or 4 with the die?

Two dice are thrown simultaneously 500 times. Each time the sum of two numbers appearing on their tops is noted and recorded as given in the following table: If the dice are thrown once more, what is the probability of getting a sum: 3

Two dice are thrown simultaneously 500 ties. Each time the sum of two numbers appearing on their tops is noted and recorded as given in the following table: If the dice are thrown once more, what is the probability of getting a sum: more than 10
