Answer: 82%
Step-by-step explanation:
The probability of getting a not clear marble out of the bag is given by the following expression
[tex]P=\frac{not clear marbles}{all the possibilities}[/tex]
The number of not clear marbles in this case, will be the sum of black and white one (15+12=27), and all the possibilities will be the sum of the black, white and clear ones (15+17+6=33). Therefore the probability will be
[tex]P=\frac{not clear marbles}{all the possibilities}=\frac{27}{33}=0.8181[/tex]
In percentage and rounding to the closest number the probability will be 82%
