Answer:
The probability of 2 or more errors is 0.018.
Step-by-step explanation:
Let <em>X</em> = number of typographical errors on a page of a certain magazine.
The expected number of errors is, <em>λ</em> = 0.2.
The random variable <em>X</em> follows a Poisson distribution with parameter <em>λ</em> = 0.2.
The probability mass function of <em>X </em>is:
Compute the probability of 2 or more errors as follows:
P (X ≥ 2) = 1 - P (X < 2)
= 1 - P (X = 0) - P (X = 1)
Thus, the probability of 2 or more errors is 0.018.

I hope my answer will help you and i guess it's correct
The Range of a function is the set of all values that that function can take.
Given the sine function f(x)=sinx,
This function is the function which calculates the sine of the values of x.
According to the definition of the sine of an angle x in the unit circle,
,
so the sine of an angle is always larger or equal to -1, and smaller or equal to 1.
This means that the values that the sine function takes are any values between -1 and 1, inclusive.
This determines the Range of the sine function.
So the Range of the sine function is [-1, 1]
