A bag contains eight blue marbles six Green marbles 12 yellow marbles and 10 orange marbles a marble is drawn at random from the bag what is the probability that the marble drone will not be blue

28/36=7/9
explanation

hope that helped

The probability that the marble drawn will not be blue is 7/9
Step-by-step explanation:
We have been given that
Number of blue marbles = 8
Total number of marbles = 8 + 6 + 12 +10 = 36
Probability of an event E is given by the formula

Here, we have
n(E) = 8
n (S) = 36
Hence, the probability of getting a blue marble is
P/E =8/36
Therefore, probability that the marble drawn will not be blue is given by
1 -p(e)
=1 -2/9
=7/9
