Answer:

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

Step-by-step explanation:

Given

The attached plot

Required

P(Ice Cream|Frogtown)

This is calculated as:

$P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}$

From the attachment;

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

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

So, we have:

$P(Ice Cream|Frogtown) = \frac{P(Ice\ Cream\ n\ Frogtown)}{P(Frogtown)}$

$P(Ice Cream|Frogtown) = \frac{0.31}{0.46}$

$P(Ice Cream|Frogtown) = 0.6739$

Express as percentage

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

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

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