Help pls!

Answer 1

Answer:  0.57

===================================================

Explanation:

The notation

P( Take the bus | Junior)

is the same as writing

P( Take the bus given Junior)

I replaced the vertical bar with the word "given".

Since we're given that the person is a Junior, this means we only focus on the Juniors. There are 13+20+2 = 35 Juniors and 20 of them take the bus.

20/35 = 0.5714 approximately which rounds to 0.57

This says about 57% of the Juniors take the bus.
