Answer:
The probability of picking a green is 0.4
Step-by-step explanation:
Mathematically, when we talk of the highest possibility an event can have, we have the answer as 1
Hence, when we add up all the probabilities, it is expected that we arrive at a value equal to 1
Thus, the probability of selecting each individual colors add up to 1
since we have the probability of three colors, the probability of the fourth will be the sum of the others subtracted from 1
we have the probability of picking a green as;
1 - 0.25 - 0.15 - 0.2 = 0.4
