Consider flipping a coin 5 times, and define the following
events:
A = "The very first flip is tails"
B ="The first three flips are tails"
C = "The middle (third) flip is tails"
D = "The last three flips are tails"
E = "The very last flip is tails"
(1) Which of the following collections of events (if any) are pairwise independent?
(2) Which of the following collections of events (if any) are mutually independent?
(3) Which of the following pairs of events (if any) are
conditionally independent, given the
third set?

[Counting and Probability] Consider the experiment of flipping a
coin four times.
a. Using a tree, determine the probability of one or two tails,
with a biased coin with P(H) = 2/3. Compare to the probability with
an unbiased coin
b. [Bayes’ Rule] Using the results of the part a suppose we have
two coins, one unbiased, and a biased coin with P(H) = 2/3. We
select a coin at random, flip it three times, and observe either
one or...

that
(a) you get exactly 7 heads?

Consider flipping nn times a coin. The probability for heads is
given by pp where pp is some parameter which can be chosen from the
interval (0,1)(0,1).
Write a Python code to simulate nn coin flips with heads
probability pp and compute the running proportion of heads X¯nX¯n
for nn running from 1 to 1,000 trials. Plot your results. Your plot
should illustrate how the proportion of heads appears to converge
to pp as nn approaches 1,000.

A game is to be played by first flipping a fair coin, and then
drawing balls without replacement from a bin. If you flip heads you
get to draw one ball, and if you flip tails you get two draw two
balls. The bin contains 7 red balls, and 4 white balls. Let W =
4x - 2 be your win amount, where X represents the number
of white balls drawn. What is your expected win amount on any given...

What’s the probability of flipping a coin 25 times and getting
between 32% and 50% heads. Please assume that this clearly discrete
distribution is, in fact, continuous, and use the normal
approximation.
