Answer:
She could spend $18 on each for the 4 friends
Step-by-step explanation:
100-28= 72
72/4=18
number of face cards in a deck of 52 cards = 12
total number of cards = 52
ways of choosing 'n' cards from 52 cards = ⁵²Cⁿ = 52!/(n!)(52-n)!
ways of choosing 'n' face cards = ¹²Cⁿ = 12!/(n!)(12-n)!
Probability = favorable outcomes/total outcomes
Probability of choosing n face cards = ¹²Cⁿ/⁵²Cⁿ
Probability of choosing n face cards = (12!/(n!)(12-n)!) / 52!/(n!)(52-n)!
= [ 12! * (52-n)! ]/[ (12-n)! * 52!)
Answer:
We need 1 cup of sugar to make 16 cookies.
Step-by-step explanation:
To solve this question we can use the Rule of Three technique to find out how many cups we would need for 16 cookies. We can use this technique because we are given three values and one variable and the two sets are a ratio of one another. The technique is shown in the picture below.
1 ⇒ 20 cookies
x ⇒ 16 cookies
We need 1 cup of sugar to make 16 cookies.
