A bag contains 4 blue, 5 white and 6 green balls. Two balls are drawn at random. What is the probability that one ball is white?

• (5C1*14C1)/15C2=2/3

• (5C1*10C1)/15C2=0.4761
  5C1 means selecting one white ball from five white balls
  10C1 means selecting another ball from remaining 10 balls(blue and green)
  15C2 means selecting 2 balls from total balls(i.e 15)
