Total number of balls = 4 + 5 + 6 = 15
► Let S be the sample space.
  • n(S) = Total number of ways of drawing 3 balls out of 15 = 15C3
► Let E = Event of drawing 3 balls, all of them are yellow.
  • n(E) = Number of ways of drawing 3 balls from the total 5 = 5C3
    (∵ there are 5 yellow balls in the total balls)

[∵ nCr = nC(n-r). So 5C3 = 5C2. Applying this for the ease of calculation]
