This integral turns out to have value ∫ a b 2 x d x = ( b 2 − a 2) And you can see that the probability that 0 ≤ X ≤ 1 is 1 2 − 0 2 = 1 which is comforting -- we knew X had to be in that range. ford springwood parts https://delozierfamily.net

Since our lambda deals with a one-hour interval, we can see that there are 3 one-hour intervals here. Therefore, we simply multiply 5 times 3 to get a lambda of 15. Next, we plug this into the equation. Therefore, the probability of getting 18 calls within 3 hours is about 7%.
