A particular coin is biased. Each time it is flipped, the probability of getting a head is P(H) = 0.7 Each flip is independent of the other flips. a) In a game, the coin is flipped 10 times. Let X be the total number of times the coin shows a head out of 10 flips. Calculate the following probabilities:

Can you answer the part b,Please. Can you use the Rstudio to figture this question. Thank you so much.

A particular coin is biased. Each time it is flipped, the probability of getting a head is P(H) = 0.7 . Each flip is independent of the
other flips.
a) In a game, the coin is flipped 10 times. Let X be the total number of times the coin shows a head out of 10 flips. Calculate the
following probabilities:
i) What is the probability of getting exactly 4 heads?
0.0368
ii) What is the probability of getting at most 4 heads?
0.0473
(Enter your answer correct to at least 3 decimal places)
iii) What is the probability of getting more than 4 heads?
0.9527
i) Compute the expected value.
"X=
ii) Compute the variance.
=
(Enter your answer correct to at least 3 decimal places)
b) We now want to compute the expected value and variance of X.
