check the picture below.
recall that a cube sides are all equal in length, and it's really just 6 squares stacked up to each other at the edges.
so if 600 is the total area of those 6 squares, then just for one is 600/6 in².
WE need to find the probability (
We know
P()=
First we find P(Boy)
From the table we can see that we have 12 boys out of (12+18=30) students
So P(Boy) =
Now we find the intersection of Junior and Boy
WE look at the Junior row and boys column that is 2
{P(Junior ∩ Boy) =
P()=
P()=
= =
P() =
