Question 1121570: A canvas manufacturer has to adjust the price of the canvas it sells according to how many flaws are present. The manufacturer uses a statistical model to predict numbers of flaws and hence sales revenue. The model assumes that there will be an average of 0.003 flaws per metre and 1000 x 0.003 = 3.0 flaws per 1000 metres.
Decide what kind of distribution is being used to model the number of flaws and use this to find the probability of more than 2 flaws in one 1000m length of canvas.
Enter your answer, correct to 3 decimal places, into the box below
Thanks in advance

Poisson distribution with discrete, random, proportional to time, theoretically independent variables.
parameter 3
probability >2 is 1-prob (0,1,2)
From the table, cumulative probability of 2 is 0.423
answer is 1-0.423 or 0.577 probability
