Problema Solution
a bag contains 8 black and 6 white balls. 2 balls are drawn at random one after the other without replacement. calculate the probabilities that the second ball is black and the first ball is white
Answer provided by our tutors
8+6=14 total balls for the first draw, therefore 13 total balls for the second draw
first draw, probability of white:
6/14 = 0.4285
second draw, probability of black:
8/13 = 0.6153
for the first draw, there is approximately a 43% probability of drawing a white ball
for the second draw, there is approximately a 62% probability of drawing a black ball
