Given 5 blue marbles, 3 red marbles and 2 white marbles. find the probability of choosing a red marble given that its not white

The chances you will get a red marble over a white or blue marble is 30%

Step-by-step explanation:

If you add 5 + 3 + 2 you will get 10

You then turn it into a fraction

3/10 is the chance you will get a red over a blue or white, now we need to convert it into a percentage by turning to 10 into 100 and multiplying 3 x 10

Once you have done that you should have 30/100

Take the 100 away and turn it into a percentage

The answer would be 30%

answer: the first graph
