A poker deck consists of cards ranked 2,3,4,5,6,7,8,9,10,J, Q,K, A, (13 different ranks) each in four suits, for a total of 52 distinct cards. A pinochle deck consists of two copies each of cards ranked 9,10,J, Q,K, A, each in four suits, for a total of 48 cards (24 pairs of identical cards).What is the probability that a five-card poker hand drawn from a pinochle deck contains no duplicate cards?

I'm terrible at math any here is appreciated.

Abucket of paint has spilled on a tile floor. the paint flow can be expressed with the function p(t) = 6(t), where t represents time in minutes and p represents how far the paint is spreading. the flowing paint is creating a circular pattern on the tile. the area of the pattern can be expressed as a(p) = 3.14(p)^2 part a: find the area of the circle of spilled paint as a function of time, or a[p(t)]. show your work. part b: how large is the area of spilled paint after 8 minutes? you may use 3.14 to approximate pi in this problem.
