Question

flip a fair coin 13. find the probability of getting at most 2 heads

Answer #1

If you flip a fair coin 20 times, find the probability of
getting at most 5 heads. Round your answer to 3 decimal places.

A fair coin is tossed 8 times. Find the probability of getting
exactly 4 heads.

You repeatedly flip a coin, whose probability of heads is p =
0.6, until getting a head immediately followed by a tail. Find the
expected number of flips you need to do.

1. what is the empirical probability of getting 4 heads in 10
flips?
2. Find the empirical probability for getting 7 heads in 10 coin
flip.

If you flip a fair coin and get heads 10 times in a row, what is
the chance of getting tails on the next flip? Explain.

Consider two coins, one fair and one unfair. The probability of
getting heads on a given flip of the unfair coin is 0.10. You are
given one of these coins and will gather information about your
coin by flipping it. Based on your flip results, you will infer
which of the coins you were given. At the end of the question,
which coin you were given will be revealed.
When you flip your coin, your result is based on a...

You flip a coin until getting heads. Let X be the number of coin
flips.
a. What is the probability that you flip the coin at least 8
times?
b. What is the probability that you flip the coin at least 8
times given that the first, third, and fifth flips were all
tails?
c. You flip three coins. Let X be the total number of heads. You
then roll X standard dice. Let Y be the sum of those...

Suppose a fair coin is tossed 64 times. The approximate probability
of getting at most 40 heads is given by

You are flipping a fair coin with one side heads, and the other
tails. You flip it 30 times.
a) What probability distribution would the above most closely
resemble?
b) If 8 out of 30 flips were heads, what is the probability of
the next flip coming up heads?
c) What is the probability that out of 30 flips, not more than
15 come up heads?
d) What is the probability that at least 15 out 30 flips are
heads?...
