The Normal probability distribution function is left-skewed, right-skewed, or symmetric depending on the values of the variance and the standard deviation might the mean of a probability distribution for a discrete random variable be less than (or greater than) the average of possible values.
A probability distribution is a mathematical function that describes the probabilities of different possible values of a variable. Probability distributions are often represented using graphs or probability tables.
Probability distributions are called discrete probability distributions, and the set of outcomes is inherently discrete. For example, if you roll a die, all possible outcomes are discrete and you get a large number of outcomes. Also called probability mass function.

Hello from MrBillDoesMath!
Answer:
Choice E.
Discussion:
Assuming that n >=1, a(n) = 4n -1, then
a(10) = 4(10) - 1 = 39
but that doesn't match any of the answers...... hmm...
BUT
If you meant that a(n) = 4^(n-1), then
a(10) = 4^(10-1) = 4^9 = 262144
which is Choice E.
Thank you,
MrB
Value of expression 
is 
.
<u>Step-by-step explanation:</u>
Here we need to evaluate expression : (3xy/3x^2-12)*(x^2+3x+2/xy+y) or ,
Let's simplify this
⇒ 
Factorizing the terms we get:
⇒ 
{ 
}
⇒ 
⇒ 
Cancelling similar terms we get:
⇒
Therefore , Value of expression is .
