    16 non cream flavor out of 30 total \[\Large P(\text{not cream flavored})=\frac{\text{number of non-cream flavor}}{\text{number total}}\] \[\Large P(\text{not cream flavored})=\frac{16}{30}\] \[\Large P(\text{not cream flavored})=\frac{8}{15}\]

    Or you can do it this way \[\Large P(\text{not cream flavored})=1 - P(\text{Cream flavor})\] \[\Large P(\text{not cream flavored})=1 - \frac{\text{number of cream flavor}}{\text{number total}}\] \[\Large P(\text{not cream flavored})=1 - \frac{14}{30}\] \[\Large P(\text{not cream flavored})=\frac{30}{30} - \frac{14}{30}\] \[\Large P(\text{not cream flavored})=\frac{30-14}{30}\] \[\Large P(\text{not cream flavored})=\frac{16}{30}\] \[\Large P(\text{not cream flavored})=\frac{8}{15}\] So you get the same answer either way
