Question

A trader has 100 mangoes for sale. Twenty of them are unripe. Another five of them are bad. If he picks a mango is at random, find the probability that it is : a) unripe? b) bad? c) neither unripe nor bad? If he picked 20 of them mangoes at random, how many would you expect to be : d) unripe ? e) bad?

Answer 1

Answer:

Step-by-step explanation:

a) unripe=20/100=1/5(when simplified)

b)bad=5/100=1/20

c) neither unripe nor bad=100-[20+5]

                                         =100-25=75

=75/100=3/4

d)unripe=20/1*1/5

             =4 mangoes

e)bad=20/1*1/20

         =1 mango
