Total marbles : 33
W + G marbles : 11
Probability of picking either a W or G : 11/33
Number of W or G marbles = 11/33 × 45 = 15
The correct answer would be 9
We have to do BIMDAS
so starting with the brackets we do
35+27
which is 62
62÷4×12
then we work left to right for multiplication and division
62÷4
which is 15.5
then we finish with 15.5×12
which is 186
hope it helps.
