If you select a ball randomly from the container of 43, what color are you most likely to draw

What colors are there and how many of each color?

That depends on what colors are in the container, and how many balls

of each color.

For example:

If all 43 balls are yellow, then the probability of randomly selecting a yellow ball

from the container is 100%, whereas the probability of randomly selecting a

green ball from the selfsame container is zero.

It all depends.
