**Statistics**

(52!)/(5!47!) or 52C5 = 2,598,960 different ways a 5-card hand can be dealt from a deck of 52 cards. (4C1)x(48C4) = the amount containing at most one ace. (5C4)x(47C1) = amount containing cards of all four suits. (not very sure of this answer)

**algebra**

ohw... sorry for that... for clarification, it's: {(c-1)x^2+2cx+c+4<or=0 { cx^2 + 2(c+1)x+(c+1)>or=0

**algebra**

Consider the following system of inequalities: {(c-1)x^2+2cx+c+4<0 { cx^2 + 2(c+1)x+(c+1)>0 The sum of all real values of c, such that the system has a unique solution, can be written as ab, where a and b are coprime positive integers. What is the value of a+b? Details a...
