 Hi and how are you all today? My name is Priyanka. The question to be discussed is, in a cricket match, a batswoman hits a boundary 6 times out of 30 balls. She plays. Find the probability that she did not hit a boundary. Now, for proceeding on with the solution, we should be firstly well versed with the term probability. Probability means doubts or chances that is used in some uncertain conditions. Like, for example, the probability range today. Now here, probability means there is a prediction that the rain can be occurred, but it's not a sure condition. So predictions are made on the basis of these probable chances. Now here, in context to this question, whenever we need to find out the probability of occurring an event or not, the formula that we will be using is, now the formula says that probability that an event will occur is equal to number of favorable outcomes divided by total number of outcomes. So this formula will be more clear to you once you will use it in this question. So now let us reread this question. Now here, we are talking about 30 balls. So that means the total number of outcomes of this event will be out of 30 balls. She can hit a boundary, right? So what you all need to do is with these 30 balls. Further, six times she is hitting a boundary. So number of times she hits a boundary is equal to six times. Now if you carefully see in this question, we are required to find the probability that she did not hit a boundary. So if she is hitting a boundary six times, then number of times she did not hit a boundary will be out of these 30 balls. She is hitting six times a boundary. So that means she is not hitting a boundary in 24 balls. So our required probability that she did not hit a boundary is equal to 24 times out of 30. So on dividing, we have four upon five. So this is our required probability that out of five times, in four times she is not hitting a boundary, right? This completes my session. Hope you have a good time. Take care.
