Use a random number generator to simulate the roll of a fair die 100 times. Let the number face up on the die represent the variable X
A. Build a relative frequency table of the outcomes of the variable X.
X
Freq
Rel. Freq
B. Use the relative frequency distribution from part c to estimate the probability of an even number face up, then find the actual probability using the probability distribution and comment on the difference in values.

throws <- sample(1:6, 100, replace=TRUE, prob=c(1,1,1,1,1,1)/6 )
table(throws)
throws
1 2 3 4 5 6
13 21 14 19 15 18
| x | f | rel.freq. |
| 1 | 13 | 0.13 |
| 2 | 21 | 0.21 |
| 3 | 14 | 0.14 |
| 4 | 19 | 0.19 |
| 5 | 15 | 0.15 |
| 6 | 18 | 0.18 |
probability of even number using relative frequency distribution = 0.21+0.19+0.18=0.58
actual probability = 0.5

You are to roll a fair die n=123 times, each time observing the number of dots appearing on the topside of the die. The number of dots showing on the topside of toss i is a random variable represented by Xi, i=1,2,⋯,123. (a) Consider the distribution of the random variable Xi. Find the mean and the standard deviation of the number of dots showing on the uppermost face of a single roll of this die. μXi= (at least one decimal)...

Example 5.5. We roll a fair die then toss a coin the number of times shown on the die. What is the probability of the event A that all coin tosses result in heads? One could use the state space Ω = {(1, H), (1, T), (2, H, H), (2, T, T), (2, T, H), (2, H, T), . . . }. However, the outcomes are then not all equally likely. Instead, we continue the state space is Ω {1,...

4. We want to test whether a die is fair. We roll it 300 times and records the outcomes as meaning we rolled a 1 on the die 54 times, etc. (a) A fair die has probability 1/6 for each of the six outcomes. Use a chi-squared test to test whether or not the probabilities are all equal. (b) An oblong die will have P(1) = P(6), P(2) = P(5) and P(3) = P(4), but all of the probabilities will...

We roll a fair 8-sided die five times. (A fair 8-sided die is equally likely to be 1, 2, 3, 4, 5, 6, 7, or 8.) (a) What is the probability that at least one of the rolls is a 3? (b) Let X be the number of different values rolled. For example, if the five rolls are 2, 3, 8, 8, 7, then X = 4 (since four different values were rolled: 2,3,7,8). Find E[X].
