Answer 1

`0.4\%`

Explanation:

Given: 60% of the boys play baseball and 24% of the boys play baseball and football in Seaton Park School

To find: percentage of those that play baseball also play football

Solution:

Let B denotes boys who play baseball and F denotes boys who play football.

`P(B)=60\%`

`P(F\cap B)=24\%`

Percentage of those that play baseball also play football =
`P\left ( F|B \right )=(P(F\cap B))/(P(B))=(24)/(60)=(2)/(5)=0.4\%`
