A repairman services five washing machines each day. For each machine, there is a 50% chance that the repair will involve installing a specific part. Find the probability that at most one washing machine out of the five will need this part for installation.

Find the probability that at most one washing machine out of the five will need this part for installation. A shopkeeper has five red, four black and two blue pens. A customer went to his shop and selects three pens at random. Find the total number of ways in which the customer can select the pens of different colours. A box contains 10 red balls and 3 blue balls. Four balls are drawn at random from the urn without replacement. Let the random variable *X* denote the number of red balls that are drawn from the box. Find the possible values that *X* can take.
