probability of not picking exactly two tulips = probability of picking exactly one tulip and one other flower + probability of picking no tulips at all
probability of picking exactly one tulip and other flower = 2/8 * 6/7 = 12/56
probability of picking no tulips at all= 6/8 * 5/7 = 30/56
addition = 42/56 = 3/4.
so the answer is 3/4
probability of picking exactly one tulip and other flower = 2/8 * 6/7 = 12/56

addition = 42/56 = 3/4.
so the answer is 3/4
I did the same way but we never considered that there are 2 ways we can get exactly one tulip either in the first attempt or 2nd.
so it will be 12/56 + 30/56 + 12/56= 27/28
