Consider a game which involves rolling three dice. Write the R code for
the following.
Using the rollDie function from the prob library, setup the sample space
for this experiment with the probability space.For each of the following
scenarios from a) through e), show the corresponding outcomes and
the probability of that event. The sample outputs for b) are shown asexample.
a) The sum of the rolls is greater than 10.
b) All the three rolls are identical.
Sample Output for outcomes:
X1 X2 X3 probs
1 1 1 1 0.00463
44 2 2 2 0.00463
87 3 3 3 0.00463
130 4 4 4 0.00463
173 5 5 5 0.00463
216 6 6 6 0.00463
Sample Output for probability: 0.02778
c) Only two of the three rolls are identical.
d) None of the three rolls are identical.
e) Only two of the three rolls are identical given that the sum of the rolls
is greater than 10.
f) Add a random variable to the sample space for the sum of the rolls.
Show the marginal distribution of this random variable. Using this
random variable, what is the probability that the sum of the rolls is
greater than 10.
g) Add a random variable to the sample space for determining whether
all the rolls are identical. Show the marginal distribution of this random
variable. Using this random variable, what is the probability that all the
rolls are identical.
h) Add a random variable to the sample space for determining if only two
out of the three rolls are identical. Show the marginal distribution of this
random variable. Using this random variable, what is the probability that
only two out of the three are identical.
i) Add a random variable to the sample space for determining if none of
the three rolls are identical. Show the marginal distribution of this random
variable. Using this random variable, what is the probability that none of
the three are identical.
Please take a look the question above and please provide the R code detail as much as possible.
