What is the probability of drawing yellow marble followed by a red marble from a bag containing 12 yellow marbles, 16 red marbles, and 15 green marbles if the first marble is not replaced?

12 +16 +15 = 43 total marbles

12 are yellow so first pick you have 12/43 probability of picking yellow

 without replacement there would be 42 marbles left

 there are 16 red ones so you  have a 16/42, reduces to 8/21 probability of picking red

 probability of picking yellow then red =

12/43 x 8/21 = 96/903, reduces to 32/301 probability

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
