A farmer has a certain number of cows and chickens in his barn. If there are 34 heads and 94 legs present, how many cows and how many chickens are in the barn

In an experiment you are to flip a two sided coin 100 times and record 55 heads up and 45 tails up determine the theoretical and experimental probability of getting a heads up in the experiment.

The ratios 3: 9, 4: 12, 5: 15, and 6: 18 are a pattern of equivalent ratios in the ratio table. which is another ratio in this pattern?
