Four identical six-sided dice, each with faces marked 1 to 6 are rolled 200 times. At each rolling, a record is made of the number of dies whose score on the uppermost face is even. The result is as follows.

No. Of even score, Xi Frequency, fi
0 10
1 41
2 70
3 57
4 22

a) Explain why the binomial model might describe the distribution of X.

b) Perform the ?2 -test at ? = 0.05 to test whether the sample used comes from a binomial.

(5) A fair 6-sided dice is rolled twice. The fairness of the dice consists of the following facts: (i) no face of the dice is likelier to be rolled than any other (so a roll of a 5 and a roll of a 3 are equiprobable) and (ii) the dice has no “memory” - each roll is independent of any other. 5.1: What is the probability that you’ve first rolled a 3 and the pair of rolls sums to something...

A six sided die is rolled 4 times. The number of 2's rolled is counted as a success. Construct a probability distribution for the random variable. # of 2's P(X) Would this be considered a binomial random variable?    What is the probability that you will roll a die 4 times and get a 2 only once? d) Is it unusual to get no 2s when rolling a die 4 times? Why or why not? Use probabilities to explain.
