17/(17+27) = 17/44 = 0.386 Odds of 3:4 mean there are 3 chances in favor, and 4 against, for a total of 7. The probability is 3/7, because it will happen only 3/7 of the time. (yes=3, no=4)

**Math**

correct

**Math**

P(?)=1-P(A) one or the other must happen, so their probabilities must sum to 1.

hmmm. what is a protector? Do you mean protractor? If so, then it is a half circle, and the perimeter p = ?r. Unless you also include the straight side, in which case p = 2r+?r.

Your answer is not even a probability. It is the number of ways to pick cards. The cards can be DDC: 13/52 * 12/51 * 13/50 DCD: 13/52 * 13/51 * 12/50 CDD: 13/52 * 13/51 * 12/50 = 3*(13*13*12)/(52*51*50) = 39/850

If (6-x-x^2) divides g(x), then that means that (3+x) and (x-2) are both factors of g(x) g(x)/(x+3) has a remainder of -27a-3b+27 g(x)/(x-2) has a remainder of 8a+2b+2 Since those are both zero, we have 9a+b = 9 4a+b = -1 a=2, b=-9 g(x) = 2x^3+5x^2-9x-18 = (2x+3)(x-2)(x+3)
