Answer:
Step-by-step explanation:
Given that Saguaro cacti are large cacti indigenous to thesouthwestern United States and Mexico. Assume that thenumber of saguaro cacti in a region follows a Poisson distribution with a mean of 280 per square kilometer.
a) Mean number of cacti per 10,000 square meters=280*10000 = 2800000
b) P(no cacti in 10000) sq m = P(X=0) for Poisson with parameter 2800000
= 0
(almost uncertain event)
c) Area of a region such that the probability of at least twocacti in the region is 0.9.
We get this is possible if mean = 8.4 for Poisson
i.e. region should have area as
