This problem relies on the definition of a Binomial random variable as a sum of n Bernoulli random variables. Let Xi be a Bernoulli random variable with p=0.1, for 1≤i≤400. The random variable X1+⋯+X400 will likely be around , give or take about . (Enter the expected value of the random variable, and its standard error.) What is the probability that X1+⋯+X400 will equal 25?

30 points! here is a you are the new manager at trusty goods wholesale produce. you need to figure out how to adjust the amount of produce in your notes after the events of the day: you got 5 more crates of bananas someone returned 2 crates of apples a worker dropped a crate of grapes (oh no! , you had to throw them out) you sold a crate of bananas you sold 5 crates of apples can you write an expression to describe your day using: "a" for crates of apples "b" for crates of bananas and "g" for crates of grapes? make sure the expression is in simplest form question 2 (3 points) explain your steps using sentences.
