Ajar contains 4 brown marbles and 9 yellow marbles.
event a = drawing a yellow marble on the first draw
event b = drawing a brown marble on the second draw
if two marbles are drawn from the jar, one after the other without replacement, what is p(a and b) expressed in simplest form?

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry

d 600 because 15*10*2=300

300+300=600
