(a)
To find: that for the first time on what roll a 6 will be entitled to get.
(a)
Answer to Problem 33RE
6
Explanation of Solution
Probability of occurring 6
Suppose X is number of times roll to get first 6
X is geom(6)
Number of rolls expected
It can be expected to roll 6 times for getting first 6
(b)
To find: the expected score on the basis of provided information.
(b)
Answer to Problem 33RE
4.17
Explanation of Solution
Given:
Rolled number of times is 6-1 =5.
Calculation:
Suppose X get any number other than 6.
Now
Expected score is 4.17.
(c)
To find: the probability that, without having a 6, will roll that many times.
(c)
Answer to Problem 33RE
5/6
