Answer:

The probability that occurrence of 8 in ten minutes is 0.0771.

Step-by-step explanation:

Poisson Distribution:

A discrete random variable X having the enumerable set {0,1,2,.....} as the spectrum, is said to have Poisson distribution with parameter $\mu$ (>0), if the p.m.f is given by

$P(X=x)=\frac{e^{-mu}\mu^x}{x!}$ for x=0,1,2,...

= 0, elsewhere

The mean number of occurrences in ten minutes is 5.3.

Here $\mu$ = 5.3 and x= 8

$P(X=8)=\frac{e^{-5.3}(5.3)^8}{8!}$

=0.0771

The probability that occurrence of 8 in ten minutes is 0.0771.

My friend sets out walking at a speed of $3$ miles per hour. I set out behind her $5$ minutes later at $4$ miles per hour. When

Answer: The answer is 0.25 miles.

Step-by-step explanation: Given that my friend started walking at a speed of 3 miles per hour and I started 5 minutes after him at a speed of 4 miles per hour. We need to find the number of miles my friend travelled when I started walking.

Since I started 5 minutes after than my friend, so we are to find the distance travelled by my friend in 5 minutes.

In 1 hour, i.e., 60 minutes, distance travelled by my friend = 3 miles.

In 1 minute, distance travelled by my friend is

$\dfrac{3}{60}=\dfrac{1}{20}~\textup{miles}.$
