Suppose that on the average, 7 students enrolled in a small liberal arts college have their automobiles stolen during the semest

Galina-37 [17]

Answer:

$P(x>1)=0.9927$

Step-by-step explanation:

From the question we are told that:

Mean $\=x =7$

Generally the Poisson equation for \=x is mathematically given by

$P(x>1)=1-P(x \leq 1)$

Therefor

$P(x>1)=1-(\frac{e^{-7}*7^0}{0!}+{\frac{e^{-7}*7^1}{1!})$

$P(x>1)=1-(9.1*10^{-4}+6.3*10^{-3})$

$P(x>1)=1-(7.3*10^{-3}$

$P(x>1)=0.9927$

Which ratio does not belong with the other three, explain your reasoning. 4/10, 2/5, 3/5, 6/15

Serhud [2]

3/5 does nor belong, as the other three fractions are just different versions of the same fraction :) 4/10 can be simplified into 2/5. If you multiply this fraction by three, 2/5 would become 6/15 :) Hope this helped!!
