Flipping 100 coins

If you wanted to simulate flipping a fair coin 100 times, you could either run the function 100 times or, more simply, adjust the size argument, which governs how many samples to draw. Since there are only two elements in outcomes, the probability that we “flip” a coin and it lands heads is 0.5.

Suppose again that you have a hat with two slips of paper in it: one slip says “heads” and the other says “tails”. Therefore at each draw, the probability of drawing a chip that says “head” is 50%, and “tail” is 50%. The replace = TRUE argument indicates we put the chip back in the hat before drawing again, therefore always keeping the 50/50 odds.

Simulate flipping a fair coin 100 times with the sample() function by setting the size to 100. Assign the result to sim_fair_coin.
Inspect the results by printing the object and using the table() function to count the amounts of heads and tails.
