Answer:
-1, 0, 1, 2, 3
Step-by-step explanation:
To answer this you have to understand 2 main things
These are: the symbols and what an integer is.
An integer is simply a whole number. For example: 1, 10, 3 etc.
The symbols, <= (first symbol) and < (second symbol) are very important. These tell us the range X is in.
<= means less than or equal to.
< means less than.
So we can write: -1 is less than or equal to x and x is less than 4.
If we follow this and also keep in mind we only want whole numbers then we can see the lowest X can be is -1 and the highest it can be is 3 since it has to be less than 4.
Then it is also everything inbetween them which is:
-1, 0, 1, 2, 3

Answer:
a) 2450
b) 1890
c) 1050
Step-by-step explanation:
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
