A bag has 12 balls colored yellow, blue, green and red. The number of balls of each colour is the same. A ball is drawn from the bag. Calculate the probability of drawing a yellow ball, a blue ball, a green ball and a red ball.

### Asked by Topperlearning User | 13th Oct, 2014, 04:16: PM

Total number of balls = 12

It is also given that the bag contains equal number of balls of each of the four colours (yellow, blue, green and red).

Therefore,

Number of yellow balls = Number of blue balls = Number of green balls = Number of red balls = 3

P(yellow) =

P(blue) =

P(green) =

P(red) =
