Answer:
A = choosing a red marble
B = choosing a green marble
Probability of A happening = P(A) = 5/(3+5+4) = 5/12
Probability of B happening = P(B) = 4/(3+5+4) = 4/12
Probability of either happening = P(A) + P(B) = 5/12 + 4/12 = 7/12
The key word in their question is red OR green and that is why we add the two probabilities. If they ask the probability of them both happening (if they said red AND green), you would multiply P(A)*P(B).
Answer:
21/50 or 21:50
Step-by-step explanation:
1km = 1000m
That means one meter is equal to 1/1000 of a km.
420 meters is 420/1000 of a km which is equal to 42/100 = 21/50 or 21:50
Is it right?
