 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 likely outcomes. 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.
