7. Defects in poured metal caused by contamination follows a Poisson distribution with average number of occurrences being 2 per cubic millimeter. What is the probability that there will be at least three defects in a randomly selected cubic millimeter of this metal

Step-by-step explanation:

If the number of defects in poured metal follows a Poisson distribution, the probability that x defects occurs is:

Where x is bigger or equal to zero and m is the average. So replacing m by 2, we get that the probability is equal to:

Finally, the probability that there will be at least three defects in a randomly selected cubic millimeter of this metal is equal to:

Where

So, P(0), P(1) and P(2) are equal to:

Finally, and are equal to:

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

x = 23.78
