2. Express House Delivery Service provides high quality service to customers. The companyguarantees a refund of all charges if a package it is delivering does not arrive at its destination by thespecified time. It is known from past data that despite all efforts, 2% of the packages mailed throughthis company do not arrive at their destinations within the specified time. Suppose a corporation mails10 packages through Express House Delivery Service on a certain day.a) Write down the appropriate probability distribution with its parameters.b) What is the probability that exactly one of these 10 packages will not arrive at its destinationwithin the specified time?c) Find the probability that at most two of these 10 packages will not arrive at its destination withinthe specified time.F280F3aF4F5F6138

There are two boxes. In each box there are 4 cards with a different number printed on it. The four cards have been numbered as 1,2,3,4 in each box. Two cards are drawn random from each box. The random variable X represents the difference between the number on the card from box 1 minus the number on the card from box 2.a) Find the mean of this probability distribution. (i.e. Find E[X] )b) Find the variance and standard deviation of this probability distribution.(i.e. Find V[X] and SD[X])The random variables M and W are defined as follows:M = X+5 and W = (1/2)X+5c) Find E[M] and E[W].d) Find V[M] and V[W].e) Mary and William play a game using the cards in the above boxes. Randomly two cards are drawn, and Mary records his score using the random variable M and William uses the random variable W. They repeat this for a large number of times and compare their scores.
