# What percent of Americans live below the poverty line and only speak English at home one decimal only?

What percentage of Americans live below the poverty line and only speaks English at home? According to the Venn diagram for the two variables give ; 10.4 percent of Americans live below the poverty line and they are english speakers at home.

## What is the probability that a randomly chosen US resident makes less than \$50000 per year and assuming that income and gender are independent What is the probability that a randomly chosen US resident makes less than \$50000 per year and is female?

Assumption: The probability of an income of less than \$50,000 and being female are independent events. The same data source indicates that 71.8% of females make less than \$50,000 per year.

## What is the probability that a randomly chosen US resident makes less than \$50000 per year and is female?

c The probability that a randomly chosen US resident makes less than \$50,000 ## per year and is female is 62.2% x 41% = 25.5% ## Assuming income is independent of gender ## 6.

## What is the relationship between living below the poverty line and speaking a foreign language at home?

The 2010 American Community Survey estimates that 14.6% of Americans live below the poverty line, 20.7% speak a language other than English (foreign language) at home, and 4.2% fall into both categories.

## Can you compute P A and B?

Formula for the probability of A and B (independent events): p(A and B) = p(A) * p(B). If the probability of one event doesn’t affect the other, you have an independent event. All you do is multiply the probability of one by the probability of another.

### What is the formula of PA intersection B?

We apply P(A ∩ B) formula to calculate the probability of two independent events A and B occurring together. It is given as, P(A∩B) = P(A) × P(B), where, P(A) is Probability of an event “A” and P(B) = Probability of an event “B”. You may also read,

### What is the probability of B given a?

The conditional probability of an event B is the probability that the event will occur given the knowledge that an event A has already occurred. This probability is written P(B|A), notation for the probability of B given A. Check the answer of

### What is the probability of A or B?

If events A and B are mutually exclusive, then the probability of A or B is simply: p(A or B) = p(A) + p(B).

### What does a ∩ b )' mean?

The set A ∩ B—read “A intersection B” or “the intersection of A and B”—is defined as the set composed of all elements that belong to both A and B. Thus, the intersection of the two committees in the foregoing example is the set consisting of Blanshard and Hixon. Read:

### How do you calculate a given B?

If A and B are two events in a sample space S, then the conditional probability of A given B is defined as P(A|B)=P(A∩B)P(B), when P(B)>0.

### What is a intersection b example?

For example- A = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10} , B = {2, 4, 7, 12, 14} , A ∩ B = {2, 4, 7}. Thus, A ∩ B is a subset of A, and A ∩ B is a subset of B.

### What is P A and B in probability?

Conditional probability: p(A|B) is the probability of event A occurring, given that event B occurs. … Joint probability: p(A and B). The probability of event A and event B occurring. It is the probability of the intersection of two or more events. The probability of the intersection of A and B may be written p(A ∩ B).

### What are the symbols of probability?

SymbolSymbol NameExample
P(A)probability functionP(A) = 0.5
P(A | B)conditional probability functionP(A | B) = 0.3
P(A ∪ B)probability of events unionP(A∪B) = 0.5
F(x)cumulative distribution function (cdf)

### What does P A given B mean?

P(A/B) is known as conditional probability and it means the probability of event A that depends on another event B. It is also known as “the probability of A given B”. P(A/B) Formula is used to find this conditional probability quickly.

### What is the probability at least one?

To find the probability of at least one of something, calculate the probability of none and then subtract that result from 1. That is, P(at least one) = 1 – P(none).

### How do you find probability or?

Probability OR: Calculations The formula to calculate the “or” probability of two events A and B is this: P(A OR B) = P(A) + P(B) – P(A AND B).
