Explanation:
Given : The number of yellow of candies in bag = 20
Total number of candies in bag =
![42+45+20+32=139](https://img.qammunity.org/2020/formulas/mathematics/high-school/fkrhj8j8dbyttarh4t838xdu9ojttnva0h.png)
The number of candies not yellow in bag =
![139-20=119](https://img.qammunity.org/2020/formulas/mathematics/high-school/d1zospnwwrs3a74ak2ncsia19ilw7ys72d.png)
Now, the probability that it is not yellow is given by :-
![\text{P(not yellow)}=\frac{\text{Number of not yellow candies}}{\text{Total candies}}\\\\=(119)/(139)](https://img.qammunity.org/2020/formulas/mathematics/high-school/ho2razcdonguao6o4qyrt2n3gdubwdf11h.png)
Hence, the probability that it is not yellow is
.
