Question

Dandelions are studied for their effects on crop production and lawn growth. In one region, the number of dandelions has a Poisson distribution with a mean of 6 per square meter. Find the probability of at least one dandelions in an area of 1 m2.

Select one:

a. 1.74%

b. None of other answers is neccessary true.

c. 93.80%

d. 6.20%

e. 98.26%

Answer 1

Solution : let XN poisson (9=6). - P(x-x)= e-^. 2x -6 a! S P(xox) = 2 6* we 2 ie =) dandelions in imo. need to find P(x 21) proobability of at least one P(x21): 1- P(x2) = 1- [P(x=0)] 1-0.0025 . +0.9975. = 99,95% one of the answe : foption 6] none of other CS Scanned with is a neccessary CamScanner anscens fowl.
