Question

Can you use the Rstudio to calculate some value please. Thank you!

A particular coin is biased. Each time it is flipped, the probability of a head is P (H) = 0.95 and the probability of a
tail is P(T) = 0.05. Each flip is independent of the other flips. The coin is flipped twice. Let X be the total number of
times the coin shows a head out of two flips. So the possible values of X are x = = 0, 1, or 2.
a) How would we find P(X=2) ? (Pick all right answers)
Type in Rstudio: choose(1, 1)* 0.95^0 * 0.05^2
✔ Type in Rstudio: choose(2, 2)* 0.95^2 * 0.05^0
□ P(X = 2) = (²) P(H)² (1 – P(H))²—2
○ P(X = 2) = (²)P(H)¹ (1 — P(H))²–1
Knowing that P(X = 1) = 0.095 and P(X= 2) = 0.9025 , compute the following probabilities:
P(X=0)
= 0.0025
(Enter the exact value)
b) What is the probability that X ≥ 1?
0.0025
(Enter the exact value)
c) Compute the expected value of X.
