Question

A bag contains 28 counters all of different colours. Colin chooses one counter and gives it to

Obi, and another counter and gives it to Zeema. In how many ways can Colin do this?

Answer 1

756 ways

Explanation:

Given

`Counters = 28`

`Selection = 2`

Required

Determine the number of ways

The first counter can be selected in 28 ways

The second can be selected in (28 - 1) ways

The number of selection is:

`Selection = 28 * (28 -1)`

`Selection = 28 * 27`

`Selection = 756`

Hence, number of possible selection is 756
