Given:
- Available Group = 9 M & 7 F
- Committee of= 4 M and 4 W to be formed
Find:
- (a) 2 of the men refuse to serve together?
- (a) 2 of the women refuse to serve together?
- (a) 1 man and 1 woman refuse to serve together?
Solution:
- The question pertains to a selection process, We will use combinations for each case as follows.
part a)
- Since 2 men cant be selected together. Then we have to discount for one man while selecting Man for the committee. Hence, the combinations are:
8C4 x 7C4 = 2450
part b)
- Since 2 women cant be selected together. Then we have to discount for one woman while selecting them for the committee. Hence, the combinations are:
9C4 x 6C4 = 1890
part b)
- Since 1 women and a man cant be selected together. Then we have to discount for one woman and one man while selecting them for the committee. Hence, the combinations are:
8C4 x 6C4 = 1050
Step-by-step explanation:
A real number MUST be able to be represented on a number line.
All numbers can be placed on a number line including irrational numbers.
Numbers like π can be placed between 3.13 and 3.15. It is a number.
Numbers like x or ∑ isn't a "REAL" number because it has no value.
