Answer 2

1?

Answer 3

Ok, different question.

Do you know how to determine the chance of event?

Answer 4

not really

Answer 5

You take the amount of events which chance you need to determine and divide it by the whole amount of events.

Answer 6

For example:
you need to call one certain ball - B14, but you can get any other ball including the one you need.
So there is only one event you need (to call B14) and there is 5 events in total that can happen (you call B, I, N, G or O)

Answer 7

So what are the chances of taking B14 out of 5 balls?

Answer 8

1/10

Answer 9
