In analyzing hits by certain bombs in a​ war, an area was partitioned into 572 ​regions, each with an area of 0.85km2. A total of 505 bombs hit the combined area of 572 regions. Assume that we want to find the probability that a randomly selected region had exactly hits. In applying the Poisson probability distribution​ formula, ​P(x) = ​, identify the values of ​, ​x, and . ​Also, briefly describe what each of those symbols represents.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. kevin spins the spinner 180 times. kevin determines about how many times the spinner will land on red or green, and his work is shown below. -kevin has the formula reversed; it should be the total number of sections over the number of red or green sections. -kevin should have used a 4 in the numerator because there are 2 red sections and 2 green sections. -kevin should multiply by the number of sections in the spinner rather than the total number of spins. -kevin calculated the prediction correctly and did not make any mistakes.
