since probability of double on a cube =1/6 , this follows geometric distribution with parameter p=1/6
option 1 is correct:

Which of these represents the probability of getting doubles (getting the same number on two number...
Random variable X counts the number of times doubles is rolled (i.e. the same number comes up on both dice) when two ordinary (6-sided) fair dice are rolled seven times. How many possible values does X have? a.6 b.7 c.8 d.30 e.36
A discrete probability distribution differs from a continuous probability distribution, by only taking values on a discrete set (like the whole numbers) instead of a continuous set. The geometric distribution is a discrete probability distribution which measures the number of times an experiment must be repeated before a success occurs. For example, in this problem, we will roll a fair six-sided die until the number six occurs, at which point we stop rolling. (a) If we are rolling a die,...
If you roll two six-sided dice, what is the probability of obtaining the following outcomes? a)2 or 3 b) 6 and 4 c) At least one 5 d) Two of the same number (two 1s, or two 2s, or two 3s, etc.) e) An even number on both dice f) An even number on at least one die and please show how you got the answers ex. P(something) = (1/2)*(1/3) = (1/6)
