# Question: According to Wired June 2008 35 of the world s solar

According to Wired (June 2008), 35% of the world’s solar energy cells are manufactured in China. Consider a random sample of 5 solar energy cells, and let x represent the number in the sample that are manufactured in China. In the next section, we show that the probability distribution for x is given by the formula,

a. Explain why x is a discrete random variable.

b. Find p(x) for x = 0, 1, 2, 3, 4 , and 5.

c. Show that the properties for a discrete probability distribution are satisfied.

d. Find the probability that at least 4 of the 5 solar energy cells in the sample are manufactured in China.
