<u>Given</u>:
Let the random variable x is normally distributed with mean and
We need to determine the probability of
<u>Probability of </u><u>:</u>
The formula to determine the value of is given by
Thus, we have;
Simplifying, we get;
Using the normal distribution table, the value of -2 is given by 0.0228
Thus, the value of is 0.0228
Answer:
Step-by-step explanation:
Let E be the set of all even positive integers in the universe Z of integers,
i.e
E = {2,4,6,8,10 ....∞}
be the characteristic function of E.
∴
For XE(2)
since x is an element of E (i.e the set of all even numbers)
For XE(-2)
since - 2 is less than 0 , and -2 is not an element of E
For { x ∈ Z: XE(x) = 1}
This can be read as:
x which is and element of Z such that X is also an element of x which is equal to 1.
∴
E = {2,4,6,8,10 ....∞}
