First, I add 52 to 48 to get the total amount of flowers. 52 + 48 = 100. Out of those 100, there are 48 tulips. If one flower wilted, the probability of it being a tulip would be 48/100, or 0.48. If a second flower wilted (with only 99 flowers left, and only 47 tulips left), the probability of it being a tulip is 47/99 or 0.474747... To get the probability of both of those being tulips, multiply the two together. 48/100 * 47/99 = 2256/9900 (then, simplify to 376/1650)
