Move the negative into the brackets,
positive becomes negative while two negatives make a positive.
Move the negative into the brackets,

We have been given the expression
We can rewrite the expression as
In order to simplify the given expression, we can check if we have any common terms in the numerator and denominator.
We can write the term 72 which is in the numerator as
Thus, the expression becomes
We can see that 4 is common in both numerator and denominator. Hence, we can cancel 4. Thus, we are left with
Therefore, we can rewrite the given expression as 54.
The formula for E(x) would be SUM[ X(n)P(n)] from n = 1 to n = infinity until we get the prime number
In the given problem, a 10-sided die with 1-10 numbers is rolled until we get a prime number
Prime numbers between 1-10 = 2,3,5,7 (4 prime numbers)
Non - prime numbers = 1,4,6,8,9,10( 6 non-prime number)
Let X be the number of times the die is rolled
The probability of getting a prime =
Now, the value of
E(X)=∑x.P(x) [ x-> {1, infinity}]
= P(1)X(1) +P(2)X(2)+P(3)X(3)+P(4)X(4)........+ P(n)X(n)
= 1. + 2.

+ 3.

+ 4.

.......
Hence, this is the value of E(x)
