 Hi and welcome to the session. Let us discuss the following question. Question says, a child has a dice whose six faces show the letters as given below. The dice is thrown once, what is the probability of getting A, what is the probability of getting D? First of all, let us understand that probability of occurrence of an event E denoted by P E is equal to number of outcomes favourable to E upon total number of possible outcomes. We will use this expression as our key idea to solve the given question. Let us now start with the solution. Now we know dice has six faces and in a single throw of dice we can get any one of these six letters. You know these six letters are marked on six faces of the dice. So we get total number of possible outcomes in a single throw of dice is equal to six. Now in the first part we have to find probability of getting A. Now it is given in the question that A occurs on two faces of the dice. So number of outcomes favourable to A is equal to two and we can see A can occur in two ways in a single throw of dice. So number of outcomes favourable to A is equal to two. Now we will find out probability of getting A that is P A. It is equal to total number of outcomes favourable to A upon total number of possible outcomes. Now we know number of outcomes favourable to A is equal to two and total number of possible outcomes is equal to six. So probability of getting A is equal to two upon six. Now this is further equal to one upon three. So we get probability of getting A is equal to one upon three. Now this completes the first part of the given question. Let us now start with the second part. Now we have to find probability of getting D. Now we know D can occur only in one way in a single throw of dice. So number of outcomes favourable to D is equal to one. D occurs on one phase. So number of outcomes favourable to D is equal to one. Now we have to find probability of getting D. We know probability of getting D is equal to number of outcomes favourable to D upon total number of possible outcomes. Now we know number of outcomes favourable to D is equal to one and total number of possible outcomes is equal to six. So probability of getting D is equal to one upon six. Now this completes the second part of the given question. So required answers for the first part and second part are one upon three and one upon six. This completes the session. Hope you understood the solution. Take care and keep smiling.
