Please tell all 9th chapter formulas. Share with your friends Share 0 Atul Shaw answered this Dear student,Assuming the demanded formulas are of probability chapter as the tagged chapter is Probability.Probability is a branch of mathematics that deals with the occurrence of a random event.Probability varies from 0 to 1.The possibility that there will be only two outcomes which states that an event will occur or not. If P(A) is the probabilty of happening of event A and probability of not happenning of event A is expressed as P'(A), also known ascomplement .1. Probability of event to happen P(E) =Number of favourable outcomesTotal Number of outcomes2. P(E) + P(E’) = 1eg., Find the probability of ‘getting 3 on rolling a die’ and also find its complement.Sample Space or total outcomes={1,2,3,4,5,6}Favourable outcomes={3} Probability[P(E)]=16We know that,P(E)+P'(E)=1P'(E)=1-P(E)P'(E)=1-16=56P'(E) means probability of not 3 on rolling a dieRegards 0 View Full Answer Lijin Edward answered this Please be specific about the text and chapter. 1
