There are 8 footballs in a store cupboard; one is yellow and the others are

white. A pupil takes 2 footballs out of the cupboard at random. What is the
probability that one of them is the yellow ball?

⚾️= white football (. I know It’s not)

We could re-arrange this many ways max 8 but with white each one has 8
Soo 8•7 equals 56
There is a chance in 56 times they only get the yellow ball 8 times but the white one would be chosen most of the times.

Hope this helps you.
