Question: A bag contains 6 white, 7 red and 5 black balls. if 3 balls are drawn from the bag at random without replacement, then what is the probability that all of them are white?
The probability that all three balls drawn from the bag are white is 1/56. It can be expressed as a fraction, a decimal, or a percentage (0.018, 0.018%, 1.8%). This probability is calculated as follows: to draw three white balls at random without replacement, we must select the first ball, then select the second ball from the remaining five white balls, then select the third ball from the remaining four white balls. Thus, the probability of drawing three white balls is (6/18) x (5/17) x (4/16) = 1/56.
