The average income of a town is 20 units of money if it is known that the standard deviation is 15. What is the probability that a random group of 50 individuals of this town has a total income of 1200 units of money? (two decimal places, in the format 0.XX) Answer:
Let Y,Si<n be n independent Bernoulli distributions with each one having probability of success. (ie P(Y; = 1) = }). Let X be the random variable X = Y; + Y, Y2 + Y YY; + Y YY; +YYY; ...Yn. Let n = 7 What is the probability P(X<5)? Answer:
