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 :
Since P(red) = P(yellow) , the number of time on yellow and red are same.
Answer :
Red 156
Green 240
Brown 648
Yellow 156
