5. A pair of dice is rolled until a sum of either 5 or 7 appears. Find the probability that a 5 occurs first. (Hint: Let Fn denote the event that a 5 occurs on the nth roll and no 5 or 7 occurs on the first n 1 rolls. Compute P(F) and argue that PF) is the desired probability.)
5. A pair of dice is rolled until a sum of either 5 or 7 appears. Find the probability that a 5 occurs first. (Hint: Let Fn denote the event that a 5 occurs on the nth roll and no 5 or 7 occurs on the first n 1 rolls. Compute P(Fn) and argue that Σ 1 P(F, ) is the desired probability.)

A pair of dice is rolled, and the number that appears uppermost on each die is observed. Refer to this experiment and find the probability of the given event.One die shows a 5, and the other is a number less than 2.
If a single fair die is rolled, find the probability of a 4 given that the number rolled is odd.
In an experiment, a die is rolled continually until a 6 appears, at which point the experiment stops. What is the sample space of this experiment. Let En denote the even that n rolls are necessary to complete the experiment. What points of the sample space are contained in En? Describe the event (UnEn)
Suppose a single fair die is rolled. Find the probability that it is a 4, given that it is an even number. The probability is? (Type an integer or a simplified fraction.)
6. A fair six sided die is rolled three times. Find the probability that () all three rolls are either 5 or 6 (6) all three rolls are even (c) no rolls are 5 (d) at least one roll is 5 (e) the first roll is 3, the second roll is 5 and the third roll is even
A coin is flipped and a die is rolled. Find the probability of getting a head on the coin and a 4 on the die. (round to 4 decimal places)
A die is rolled four times. Find the probability of getting 5 exactly two times.
