Three of the Christmas lights on Theo's Christmas tree have burned out and need to be replaced. He has a box of 8 replacement bulbs, 3 of which are red, 1 is blue, and the rest are green. An experiment has three bulbs removed simultaneously and at random from Theo's box and the random variable X is defined to be the number of red bulbs among the three bulbs that were removed from the box. Find the expected value of X. None of the others are correct 3/2 9/8 1/2 1/4 3/8

A poll of n voters is to be taken in an attempt to predict the outcome of a by-election in a certain riding. Specifically, you are interested in the proportion of voters that will vote for a certain candidate, Candidate A n = 430 voters have been randomly chosen, each has indicated what candidate they will vote for. You are to count the number, out of 430, who say they will vote for Candidate A. This count is measured by the random variable X. You find X = 169. (a) Find a 94% confidence interval for p, the proportion of all voters who will vote for Candidate A. Use at least four decimal points for your lower and upper bounds. Lower Bound - Upper Bound= (b) Interpret the meaning of the interval you found in part (a). The proportion of ? ✓that will vote for Candidate A is ? > % and %. (Enter your answer to at least two decimals.)
Three pancakes are at your disposal. One has a golden colour on both sides, one has a brown colour on both sides, and one has a golden colour on one side but a brown colour on the other. You randomly choose a pancake and see that one of the sides is brown. Calculate the likelihood that the pancake's opposite side is brown.
Let the random variable X denote the number of girls in a five-child family. If the probability of a female birth is 0.5, find the following probabilities. (a) Find the probability of 0, 1, 2, 3, 4, and 5 girls in a five-child family. (Round your answers to three decimal places.) P(0 girls) = P(1 girl) = P(2 girls) = P(3 girls) = P(4 girls) = P(5 girls) = (c) Compute the mean and the standard deviation of the random variable X. (Round your standard deviation to three decimal places.) mean __ girls standard deviation __ girls
A small business is studying the number of customers that enter the store. They record the number of customers entering every hour for three days, and find that 27% of the time two customers enter the store in an hour, 28% of the time of the time one customer enters the store in an hour, and the remainder of the time no one enters the store in an hour. What is the expected number of customers per hour?

Of the students in the college, 60% of the students reside in the hostel and 40% of the students are day scholars. Previous year result reports that 30% of all students who stay in the hostel scored A Grade and 20% of day scholars scored A grade. At the end of the year, one student is chosen at random and found that he/she has an A grade. What is the probability that the student is a hostlier?
