There are only red cabbages, white cabbages and green cabbages in a sack.

The ratio of the number of red cabbages to the number of white cabbages is 3:29

Puljay takes at random a cabbage from the sack.

The probability that the cabbage is green is 0.2

Work out the probability that Puljay takes a red cabbage.

Thank you!

Probability of green is .2 that means the remaining cabbages represent 0.8 of the total

3:29 is possibly 32 cabbages

32 = .8x x = 40 total cabbages

3:29 means there are 3 reds and 29 whites and 8 greens out of 40

red/40 = 3/40 = .075 chance of picking a red one
