 Hello, I welcome to the session. I am Deepika here. Let's discuss the question which says Given that E and F are events such that probability of E is equal to 0.6 probability of F is equal to 0.3 and probability of E intersection F is equal to 0.2 find probability of E upon F and probability of F upon E Let us first understand conditional probability. If E and F are two events associated with the same sample space of a random experiment, the conditional probability of the event E given that F has occurred that is probability of E upon F is given by probability of E upon F is equal to probability of E intersection F upon probability of F provided probability of F is not equal to 0 So this is a key idea behind our question We will take the help of this key idea to solve the above question. So let's start the solution Now we are given probability of E is equal to 0.6 probability of F is equal to 0.3 and probability of E intersection F is equal to 0.2 So we are given probability of E is equal to 0.6 probability of F is equal to 0.3 and probability of E intersection F is equal to 0.2 Now we have to find probability of E upon F and probability of F upon E Now according to our key idea We know that probability of E upon F is equal to probability of E intersection F upon probability of F Provided probability of F is not equal to 0. Now here we have probability of E intersection F is equal to 0.2 Probability of F is equal to 0.3 So probability of E upon F is equal to 0.2 upon 0.3 Now this is again equal to 2 over 3 Again probability of upon E is given by the formula probability of F intersection E upon probability of E Provided probability of E is not equal to 0 since probability of F intersection E is equal to probability of E intersection F therefore probability of F upon E is equal to 0.2 over probability of E which is 0.6 And this is again equal to 1 over 3. So we have probability of E upon F is equal to 2 over 3 and probability of F upon E is equal to 1 over 3 So this is the answer for the above question This completes our session. I hope the solution is clear to you. Bye and have a nice day
