Answer:
P(red marble) = 6÷15
Step-by-step explanation:
First, we add all of it we get 15.
Now the probability of getting a red marble will be = number of favorable outcomes ÷ total out comes.
Here the favorable outcomes to red is 6,and the total outcome is 15.
So it is 6÷15.
Now we took one marble. And kept it away.
Now the total number of outcomes are 15-1=14
Now the favorable outcomes for green is 7,snd total outcomes are 14.
So the probability is 7÷14.
Remember don't subtract the one marble u took in every similar question. Do it only if it is told to keep away the first marble you took.
