Answer 5

\[C _{1}^{16} \div C _{1}^{40}\]
Although this question belongs to the Mathematics section.

Answer 6

add up all the balls...(9 + 16 + 9 + 6) = 40
How many red balls are there ? There are 16 red balls.

Now put the number of red balls over the total number of balls...16/40.
Reduce that and it becomes 2/5.

Chances of drawing a red ball are 2/5.
