Answer:

Total probability value is 1

P(green) = 0.2 , P(brown) = 0.54

Given P(red) = P(yellow) = x

Total Probability = P(green) + P(Brown) + x + x

1 = 0.2 + 0.54 + 2x

1 - 0.74 = 2x

x = 0.13

P(red) = P(yellow) = 0.13

Now number of times it landed on each color :

$On \ red :\\P(red) = \frac{number \ of \ times \ on \ red}{1200} \\\\0.13 *1200 = number \ of \ times \ on \ red\\number \ of \ times \ on \ red\\ = 156\\$

Since P(red) = P(yellow) , the number of time on yellow and red are same.

$On \ yellow :\\number \ of \ times \ on \ yellow = 156$

$On \ green :\\P(green ) = \frac{number \ of \ times \ on \ green}{1200}\\\\0.2 *1200 = number \ of \ times \ on \ green\\\\number \ of \ times \ on \ green = 240$

$On \ Brown : \\P(brown) = \frac{number \ of \ times \ on \ brown}{1200}\\\\0.54 *1200 = number \ of \ times \ on \ brown\\number \ of \ times \ on \ brown = 648$
