Answer:
a) 98.01%
b) 13.53\%
c) 27.06%
Step-by-step explanation:
Since a car has 10 square feet of plastic panel, the expected value (mean) for a car to have one flaw is 10*0.02 = 0.2
If we call P(k) the probability that a car has k flaws then, as P follows a Poisson distribution with mean 0.2,
a)
In this case, we are looking for P(0)
So, the probability that a car has no flaws is 98.01%
b)
Ten cars have 100 square feet of plastic panel, so now the mean is 100*0.02 = 2 flaws every ten cars.
Now P(k) is the probability that 10 cars have k flaws and
and
And the probability that 10 cars have no flaws is 13.53%
c)
Here, we are looking for P(1) with P defined as in b)
Hence, the probability that at most one car has no flaws is 27.06%
Given number is 78/14.
We have to find two whole numbers between which given number 78/14 lies.
Let's convert that into mixed fraction.
To do that we divide 78 by 14 to find the quotient.
We see that 14 goes 5 times into 78 and leaves remainder of 8.
So we can rewrite 78/14 as .
means little more than 5 but less than 6.
So required two whole numbers are 5 and 6.
