Question

a box contains 5 blue chips and 11 red chips. a person selects two chips without replacement, find the probability of selecting 2 blue chips?

Answer 1

5 blue chips, 11 red chips.....total of 16 chips

probability of first being blue = 5/16
without replacement
probability of 2nd being blue = 4/15

probability of both : 5/16 * 4/15 = 20/240 reduces to 1/12
