please explain. Thanks

Answer #1

A fair coin is flipped six times. Find the probability that
heads comes up exactly four times.
1/16
15/64
90/16
1/4
2/3

When coin 1 is flipped, it lands on heads with probability
3/5 ; when coin 2 is flipped it lands on heads with probability
4/5 .
(a)
If coin 1 is flipped 12 times, find the probability that it
lands on heads at least 10 times.
(b)
If one of the coins is randomly selected and flipped 10 times,
what is the probability that it lands on heads exactly 7
times?
(c)
In part (b), given that the first of...

(a)
If coin 1 is flipped 11 times, find the probability that it
lands on heads at least 9 times.
(b)
If one of the coins is randomly selected and flipped 10 times,
what is the probability that it lands on heads exactly 7
times?

If a coin is flipped 3 times, what is the probability of getting
exactly 2 heads?

A biased coin is flipped 9 times. If the probability is 14 that
it will land on heads on any toss. Calculate: This is a binomial
probability question
i) The probability that it will land heads at least 4
times.
ii) The probability that it will land tails at most 2 times.
iii) The probability that it will land on heads exactly 5
times.

A coin is flipped. If a heads is flipped, then the coin is
flipped 4 more times and the number of heads flipped is noted;
otherwise (i.e., a tails is flipped on the initial flip), then the
coin is flipped 2 more times and the result of each flip (i.e.,
heads or tails) is noted successively. How many possible outcomes
are in the sample space of this experiment?

An unfair coin is flipped 3 times, heads is 4 times as likely to
occur than tails.
x= the number of heads.
Find the probability distribution, E(x), and σ(x).

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

A coin is tossed 5 times. Find the probability that exactly 2
are heads.
The probability that exactly 2 are heads is?
(Type an integer or decimal rounded to the nearest thousandth
as needed.)

A coin with two sides, heads and tails, is flipped 100 times.
What is the probability that a "heads" will come up exactly 60
times?
Submit your answer as a decimal fraction (range: 0 to
1) to five (5) decimal places.
