And so this is sometimes the event in question right over here is picking the yellow marble.
Two marbles are drawn without replacement.
If we got a red marble before then the chance of a blue marble next is 2 in 4 if we got a blue marble before then the chance of a blue marble next is 1 in 4 this is because we are removing marbles from the bag.
Divide 11 number of positive outcomes by 20 number of total events to get the probability.
So in our example the probability of drawing a white marble is 11 20.
