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

strojnjashka [21]

Answer:0.9991

Step-by-step explanation:

The Poisson distribution probability formula is given by :-

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$ , where \lambda is the mean of the distribution and x is the number of success

Given : $\lambda=7$

The probability that more than 1 student will have his automobile stolen during the current semester is given by :-

$P(x\geq1)=1-P(x=0)=1-(\dfrac{e^{-7}7^0}{0!})\\\\=1-e^{-7}=0.99908811\approx0.9991$

Hence, the probability that more than 1 student will have his automobile stolen during the current semester =0.9991

Q + 5/9= 1/6 from big ideas mathbook

Alika [10]

9We have such eqation
Q $+ \frac{5}{9} = \frac{1}{6}$ /*9 (multiply both sides by 9)
9Q+5= $\frac{9}{6}$ /-5 both sides
9Q= $\frac{9}{6}- 5$
9Q= $\frac{9}{6}- \frac{5*6}{6}$
9Q= $\frac{9-30}{6}$
9Q=- $\frac{21}{6}$ /:9 divide both sides by 9
Q=- $\frac{21}{6}:9$
Q $\frac{21}{6*9} =- \frac{21}{54}=[tex] \frac{7}{18}$ - its the answer
