Answer: 75
======================================================
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.
