Why might the mean of a probability distribution for a discrete random variable be less than (or greater than) the average of po

user100 [1]

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.

Answer:

$y=1.44$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS
Equality Properties

Step-by-step explanation:

Step 1: Define

$\frac{4.5}{y} =\frac{12.5}{4}$

Step 2: Solve for y

Cross-multiply: $4(4.5) = 12.5y$
Multiply: $18 = 12.5y$
Isolate y: $1.44 = y$
Rewrite: $y=1.44$

Step 3: Check

Plug in y to verify it's a solution.

Substitute: $\frac{4.5}{1.44} =\frac{12.5}{4}$
Divide: $3.125=3.125$

Here, we see that 3.125 does indeed equal 3.125. ∴ y = 1.44 is a solution of the equation.

A family has 4 children. find the probability that at least one of the children is a boy.

zubka84 [21]

The probability that one of the children will be a boy is 75%. This is because if the other 3 children were girls, there is no longer a 50% chance there will be a girl. The more girls, the lower the probability.

1 3/4 − 4/5 = 35 twentieths − what fraction??? Plss help will give brainliest :)

7nadin3 [17]

let's firstly convert the mixed fractions to improper fractions and then to do away with the denominators, let's multiply both sides by the LCD of all denominators.

$\stackrel{mixed}{1\frac{3}{4}}\implies \cfrac{1\cdot 4+3}{4}\implies \stackrel{improper}{\cfrac{7}{4}} \\\\[-0.35em] ~\dotfill\\\\ \cfrac{7}{4}-\cfrac{4}{5}=\cfrac{35}{20}-\boxed{?}\implies \stackrel{\textit{multipling both sides by }\stackrel{LCD}{20}}{20\left( \cfrac{7}{4}-\cfrac{4}{5} \right)=20\left( \cfrac{35}{20}-\boxed{?} \right)} \\\\\\ 35-16=35-20\boxed{?}\implies 19=35-20\boxed{?}\implies -16=-20\boxed{?} \\\\\\ \cfrac{-16}{-20}=\boxed{?}\implies \cfrac{4}{5}=\boxed{?}$
