Question

What is the probability that someone in the survey considered reading books or surf the internet as the best entertainment?

Answer 1

Answer is
`(31)/(100)`

Explanation:

values given in table

Reading books percentage is 22

hence we can write probability as

Probability (reading books) =
`(22)/(100)`

percentage of surfing internet is= 9

Probability of surfing internet is =
`(09)/(100)`

the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)

probability (reading or surf)=
`(22)/(100)`+
`(09)/(100)`

=
`(31)/(100)`

Answer 2

31/100

Explanation:

From the given table

Reading books percentage is 22

so Probability (reading books) =
`(22)/(100)`

Surf the internet percentage is 9

Probability (surf the internet) =
`(9)/(100)`

the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)

probability (reading or surf)=
`(22)/(100) +(9)/(100)`

=
`(31)/(100)`
