Assume two dice are thrown (for each bite the dust, it is similarly

likely that 1, 2, 3, 4, 5, or 6 spots will show).

a What is the likelihood that the absolute of the two dice

will amount to 7 or 11?

b What is the likelihood that the absolute of the two dice

will amount to a number other than 2 or 12?

c Are the occasions

E1 first kick the bucket shows a 3

E2 all out of the two dice is 6

free occasions?

d Are the occasions

12.4 Bayes' Rule 713

E1 first pass on shows a 3

E2 complete of the two dice is 7

autonomous occasions?

e Given that the complete of the two dice is 5, what is the

likelihood that the principal kick the bucket showed 2 spots?

f Given that the principal pass on shows 5, what is the proba-

bility that the all out of the two dice is even?
