If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the, probability of getting a green sector What is the probability of getting a non blue sector, Answer :, Total sectors=3+1+1=5, There are 5 sectors and we can get a green sector in three cases., , 3, Probability of getting a green sector = 5, , We will get a non blue sector when we will get either a green sector or a red sector. Hence, 4, cases of such type are possible in which we will get a non blue sector., , 4, Probability of getting a non blue sector = 5, , Q6:, , Find the probabilities of the events given in Question 2., , Answer :, , (i) (4) Out of 6 possible outcomes, a prime number can be obtained in three cases. Therefore,, 301, , probability of getting a prime number= 6 2, , (b) Out of 6 possible outcomes, a prime number may not be obtained in three cases., , alw, , 1, Therefore, probability of getting not a prime number = 2, , (ii) (a) Out of 6 possible outcomes, a number greater than 5 can be obtained in only 1 case., , 1, Therefore, probability of getting a number greater than 5 = 6, , b) Qué oftpbdssible@outcomes, a number not greater than 5 can be obtained in 5 cases.
