Is that the full question or does it say like a certain percent of $12.90 was color or?
I don’t get want u need help with.
First question seems incomplete :
Answer:
40 ways
Step-by-step explanation:
Question B:
Number of boys = 6
Number of girls = 4
Number of people in committee = 3
Number of ways of selecting committee with atleast 2 girls :
We either have :
(2 girls 1 boy) or (3girls 0 boy)
(4C2 * 6C1) + (4C3 * 6C0)
nCr = n! ÷ (n-r)!r!
4C2 = 4! ÷ 2!2! = 6
6C1 = 6! ÷ 5!1! = 6
4C3 = 4! ÷ 1!3! = 4
6C0 = 6! ÷ 6!0! = 1
(6 * 6) + (4 * 1)
36 + 4
= 40 ways
*looks at question for a while* .....
OH !
If you lived in Great Britain and you wanted to buy one Euro it would cost LESS THAN A POUND .
Final price = whole sale price+ 8% whole sale price
24.50 +(8/100 × 24.50)
24.50 + 196=$ 26.46
