Answer 1

`P(Ice Cream|Frogtown) = 67.4\%`

Explanation:

Given

The attached plot

Required

P(Ice Cream|Frogtown)

This is calculated as:

`P(Ice Cream|Frogtown) = (P(Ice\ Cream\ n\ Frogtown))/(P(Frogtown))`

From the attachment;

`P(Ice\ Cream\ n\ Frogtown) = 0.31`

`P(Frogtown) = 0.31 + 0.15 = 0.46`

So, we have:

`P(Ice Cream|Frogtown) = (P(Ice\ Cream\ n\ Frogtown))/(P(Frogtown))`

`P(Ice Cream|Frogtown) = (0.31)/(0.46)`

`P(Ice Cream|Frogtown) = 0.6739`

Express as percentage

`P(Ice Cream|Frogtown) = 0.6739 * 100\%`

`P(Ice Cream|Frogtown) = 67.39\%`

`P(Ice Cream|Frogtown) = 67.4\%` -- approximated
