Step-by-step explanation:
Number of women = 8
Number of men = 6
A committee consisting of 3 men and 3 women is to be formed.
(a) 2 of the men refuse to serve together.
Number of men who don't want to serve together = 2
Remaining men = 4
Total ways = Both men who don't want to serve together are not selected + only one of them is selected.
(b) 2 of the women refuse to serve together.
Number of women who don't want to serve together = 2
Remaining men = 6
Total ways = Both women who don't want to serve together are not selected + only one of them is selected.
(c)1 man and 1 woman refuse to serve together.
Ways = Total ways - Both man and woman are select who refuse the serve together
Answer:
17 pants and 9 shirts
Step-by-step explanation:
questions like this require you to guess numbers first then adjust them as needed. I originally guessed 20 pants and 6 shirts, however the number was too high, so I put less pants, since they're the higher number. if the number was too low you would use less shirts since they're the lower number. after a couple of tries you'll get
(225 × 17) + (125 × 9) = 4950
but seriously who spends almost 5000 dollars on clothes from one store in one outing, that's so much money
Answer:
The 3rd one again
Step-by-step explanation:
(a+−2)(8+−5a+3)
=(a)(8)+(a)(−5a)+(a)(3)+(−2)(8)+(−2)(−5a)+(−2)(3)
=8−5+3a−16+10a−6
=8−21+13a−6
hope this helped:)
