A jar contains 3 red, 4 blue, and 5 white marbles. What is the probability of drawing first a red and then, without replacement, a white marble? 5/44 5/48 31/44
The answer would be 5/44. Drawing red first- 3/ 3 + 4 + 5 = 3/12 Reduced to 1/4. Drawing white second- 5/ 2 + 4 + 5 = 5/11 Drawing red and then, without a replacement, a while marble- 1/4 x 5/11 = 5/44. Hope this helps.
