Total outcome 30 + 15 + 5 = 50    50C1

P(yellow) = 5C1 / 50C1

p(green) = 15C1 / 50C1

Total Prob = P(yellow) + p(green)

To find % multiply by 100

campbell_st · Answer

find the probabilities of each colour as a fraction then substitute the specific colour probability into the right hand side and multiply.

P(Yellow then Green) = P(Yellow) x P(Green)

lastly convert the fraction to a percentage

huh...Sorry it is P(yellow) x p(green)
