What is the standard deviation of the discrete probability distribution of the extra damage points? In a certain role-playing game (RPG), extra damage points are determined by rolling a 10-sided die (in which each side is labeledwith the numbers 1-10). Rolling a prime number gives 5 additional damage points while obtaining other values gives only 1bonus damage point.

* Your answer is incorrect. Service time for a customer coming through a checkout counter in a retail store is a random variable with the mean of 3.5 minutes and standard deviation of 3.5 minutes. Suppose that the distribution of service time is fairly close to a normal distribution. Suppose there are two counters in a store, n₁ = 2 customers in the first line and n₂ = 13 customers in the second line. Find the probability that the difference between the mean service time for the shorter line X₁ and the mean service time for the longer one X₂ is more than 0.1 minutes. Assume that the service times for each customer can be regarded as independent random variables. Round your answer to two decimal places (e.g. 98.76). P = i 98.80
