An experiment consists of a subset from a fixed number of objects where the order of the chosen object is not important. determine the size of the sample space when you choose the following a) 4 objects from 21b)3 objects from 27c) 5 objects from 18

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
