Answer:
Step-by-step explanation:
~
Substitute ''x'' with '2' & 'y' with "-4":-
First let's solve
Calculate exponents:- -4^5= -1024
Remove parentheses, apply rule:-
Apply fraction rule:-
Divide numbers:-
Now that we're done factoring the denominator let's bring down the numerator which is ' 1 ':-

The table of the probability is missing, so i have attached it.
Answer:
μ = 0.919
The interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.
Step-by-step explanation:
The expected value which is also called mean value is denoted by the symbol μ. It is defined as the sum of the product of each possibility x with it's probability P(x) as the formula;
μ = Σx.P(x) = (0 × 0.272) + (1 × 0.575) + (2 × 0.121) + (3 × 0.027) + (4 × 0.004) + (5 × 0.001)
μ = 0.919
Thus, the interpretation of this is that;on the average, an individual aged 15 years or older has been involved in 0.919 marriages.
