Step-by-step explanation:
Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.
That means after applying the coupon, you will only pay 90% of the original price. Which is
which equals 90 cents.
So let go back to this problem and apply similar thinking.
The price of the original root is g, so for the original price column, check the 3rd cell, g.
Use our comparision problem, by applying the coupon to the chocolate, you will save
which is 1/10 of the original price.
In this equation, we can represent this as 0.1g.
So for the second column, shade in 5th cell, 0.1g.
The price would be
So our equation for this equation will be
0.9g.
So for third column, shade in 1st cell, 0.9g.
Answer:
There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
is the Euler number
is the mean in the given time interval.
The problem states that:
The number of phone calls that Actuary Ben receives each day has a Poisson distribution with mean 0.1 during each weekday and mean 0.2 each day during the weekend.
To find the mean during the time interval, we have to find the weighed mean of calls he receives per day.
There are 5 weekdays, with a mean of 0.1 calls per day.
The weekend is 2 days long, with a mean of 0.2 calls per day.
So:
If today is Monday, what is the probability that Ben receives a total of 2 phone calls in a week?
This is . So:
There is a 0.73% probability that Ben receives a total of 2 phone calls in a week.
