Question

A shelf has 20 bags of potatoes. Two of the bags have potatoes starting to go bad.

What is the expected probability of the complement of the event "bad bags of potatoes"?

Answer 1

Total of 20 bags

2 "bad bags"

Bad/total=2/20=1/10

Theres a 10% or 1/10 chance that you will pick a bad bag

Answer 2

the expected probability will be (1/10) or 10%.

Explanation:

A shelf has 20 bags of potatoes. Two of the bags have potatoes starting to go bad.

So set of events will be n(s) = 20

and favorable event n(E) = 2

Therefore, probability of the complement of the event "bad bags potatoes" will be

P =
`(n(E))/(n(S))`

=
`(2)/(20)`

=
`(1)/(10)`

Therefore, the expected probability will be (1/10) or 10%.
