Simple probability is found by counting all the results which fit requirements and dividing by all possible results.

5/20*4/20=1/4*1/5=1/20 or 1/2
By coincidence, the same as the chance of drawing the white marble in one draw.

year 1
cost = 1.03 (1500) = 1545
put 1545 in for x in year 2
year 2
1.03 * 1545 = 1591.35
put in 1591.35 in for x in year 3
year 3
1.03 *1591.35=1639.0905
round to the nearest cent
cost in three years: $1639.09
