An urn contains 3 red, 2 white, and 1 black balls. law and robin take turns and draw balls from this urn one at a time, with no repetition (i. e. drawn balls are not put back in the urn). first person to draw a white ball wins. and if a person draws the black ball, that person loses automatically. assume that all the balls in the urn are equally likely to be drawn at any stage in this game and law is the first person to draw a ball. (a) determine the probability of law winning the game. (b) determine the probability of law winning the game, given that the first ball he drew was red. (c) determine the probability of game ending with someone drawing the black ball. (d) determine the probability of robin drawing the black ball, given that law won the game.

Evaluate 8x2 + 9x − 1 2x3 + 3x2 − 2x dx. solution since the degree of the numerator is less than the degree of the denominator, we don't need to divide. we factor the denominator as 2x3 + 3x2 − 2x = x(2x2 + 3x − 2) = x(2x − 1)(x + 2). since the denominator has three distinct linear factors, the partial fraction decomposition of the integrand has the form† 8x2 + 9x − 1 x(2x − 1)(x + 2) = correct: your answer is correct. to determine the values of a, b, and c, we multiply both sides of this equation by the product of the denominators, x(2x − 1)(x + 2), obtaining 8x2 + 9x − 1 = a correct: your answer is correct. (x + 2) + bx(x + 2) + cx(2x − 1).
