Answer» Total mangoes in box = 150Number of rotten mangoes in one box = 15 Therefore,Probability of getting rotten mangoes = 15/150 = 1/10 Then,Probability of not getting rotten mangoes = 1 - 1/10 = 9/10 In one box number of rotten mangoes are 15So, if 10 boxes are purchased then number of rotten mangoes expected = 15*10= 150

Answer»

Total mangoes in box = 150Number of rotten mangoes in one box = 15

Therefore,Probability of getting rotten mangoes = 15/150 = 1/10

Then,Probability of not getting rotten mangoes = 1 - 1/10 = 9/10

In one box number of rotten mangoes are 15So, if 10 boxes are purchased then number of rotten mangoes expected = 15*10= 150
