Find the specified probability. The number of loaves of rye bread left on the shelf of a local bakery at closing (denoted by the random variable X) varies from day to day. Past records show that the probability distribution of X is as shown in the following table. Find the probability that there will be at least three loaves left over at the end of any given day. x 0 1 2 3 4 5 6 P(X = x) 0.20 0.25 0.20 0.15 0.10 0.08 0.02 0.15 0.35 0.65 0.20

The number of loaves of rye bread left on the shelf of a local bakery at closing (denoted by the random variable X) varies from day to day. Past records show that the probability distribution of X is as shown in the following table. x | 0 | 1 | 2 | 3 | 4 | 5 | 6 p(x) | 0.20 | 0.25 | 0.20 | 0.15 | 0.10 | 0.08 | 0.02 Find the probability that there will be at least three loaves left over at the end of any given day. Find the probability that there will be at most two loaves left over at the end of any given day. Find the probability that there will be exactly five loaves left over at the end of any given day.

A local bakery has determined a probability distribution for the number of cheesecakes that they sell in a given day. The distribution is as follows: # sold per day (x) 0 5 10 20 25 P(x) 0.12 0.08 0.24 0.13 0.43 Find the EXPECTED number of cheesecakes that this bakery expects to sell in a day. Round answer to one decimal place.

Use the following information to answer the next six exercises: A baker is deciding how many batches of muffins to make to sell in his bakery. He wants to make enough to sell every one and no fewer. Through observation, the baker has established a probability distribution. $$\begin{array}{|c|c|}\hline x & {P(x)} \\ \hline 1 & {0.15} \\ \hline 2 & {0.35} \\ \hline 3 & {0.40} \\ \hline 4 & {0.10} \\ \hline\end{array}$$ Define the random variable $X$.
