Question

A box contains 150 mangoes of which 90 are good , 45 haveminor defects and 15 are rotten .what is rhe probabilityof not getting a single rotten mango in the box ?if 10 boxes are purchased ,hiw many rotten mangoes are expected

Answer 1

Probability for a non rotten mango - subtract rotten mangoes from total mangoes and find the p(E) i.e =150-15=135
P(E)=135/150=9/10


10 boxes purchased - no of rotten mangoes will be 10*15=150
And total mangoes will be 150*10=1500

Pe of getting a rotten mango is =150/1500
=1/10
