Given that customers arrat a service window according to a poisson process with an average of 0.2 per minute

=  12 per hour.

a)  the probability that the time between two successive arrivals is less than 6 minutes

= For one hour more than 60/6 =10 customers arrive.

P(X>10) = 0.6528

b) Prob that there will be exactly three arrivals during a given 10-minute period

P(x=3) for average 2

The time required to complete a job varies inversely as the number of people working. it took 4 hours for 7 electricians to wire
Solnce55 [7]
Let's assign variables

The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x

</span>
<span>y varies inversely as x

so that:
y= k\frac{1}{x}
where  k is the proportional constant


To calculate the value of k, plug in the values of x and y:
x=7
y=4

4=k (\frac{1}{7}) \\~\\k=28


Now, write down the relation between x and y:
y=28x


"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
y=(28) \frac{1}{3} = \frac{28}{3} =9 \frac{1}{3} =9.333333~~hr

So it would take 9 hours and 20 minutes to have this job done.
