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!)
I think its B
Hope it helps

Answer:
425
Step-by-step explanation:
Answer:
p + 0.11p
Step-by-step explanation:
The merchandise is marked up 11%. This means you pay 100% of the price plus 11%. We can represent that as (1+r) where r is the percent marked above. For 11%, this expression would be 1+0.11. We multiply that by the price p. p(1+0.11). This simplifies to p+0.11p. We can further simplify it to 1.11p.
P(1+r) = p(1+0.11)= p+0.11p=1.11p
