Step-by-step explanation:
Answer:
P of white: 0.26
P of green: 0.39
Step-by-step explanation:
Assume the probability of a white pin is p.
Then the probability of a green pin is (3/2)p because their ratio is 3:2.
The sum of the probabilities must be 1.
0.1+(3/2)p+0.25+p=1
(5/2)p+0.35=1
(5/2)p=0.65
p=(2/5)(0.65)=0.26
(3/2)p=0.39
