 Hello and welcome to the session today. We will discuss the following question which says from a well shuffled pack of cards A card is drawn at random find the probability of getting a black queen Let us proceed with its solution We are given that a card is drawn from a well shuffled pack of cards. So here Well shuffling ensures equally lightly Outcomes now we need to find out the probability of getting a black queen So let us assume that E is the event of Getting a black queen. There are 52 cards in a pack. So that means Number of possible outcomes will be equal to 52 And in a pack of cards, there are two black queens. So number of outcomes Favorable to the event E will be 2 We know that probability of an event E is given by Number of outcomes favorable to the event E upon Number of all possible outcomes Now here number of outcomes favorable to E are 2 So this will be equal to 2 upon number of all possible outcomes. That is 52 and This will be equal to 1 upon 26 Thus probability of getting a black queen from a well shuffled pack of cards is 1 upon 26 With this we finish this session. Hope you must have understood the question. Goodbye. Take care and have a nice day
