Python 3, include doc strings. Bias probability = 70% heads, 30% tails.

1. write a function to toss a fair coin; it should return True if the coin toss yields Heads and False if tho coin toss yields Tails 2. write a function to toss a fair coin 100 times and count the number of heads; (we will call this arn cxpcrincnt 3 write a function to repeat this experiment 1000 times, and compute the mean of the # of heads 4. compu te the standard deviation of these experiments Repeat this exercise for a biased coin, with probability p ? 10, 11 of heads
