For each set of probabilities, determine whether the events A and B are independent or dependent.
lozanna [386]

Answers:

  • (a) Independent
  • (b) Dependent
  • (c) Dependent
  • (d) Independent

========================================================

Explanation:

If events A and B are independent, then the two following equations must both be true

  • P(A | B) = P(A)
  • P(B | A) = P(B)

This is because the conditional probability P(A|B) means "P(A) when B has happened". If B were to happen, then P(A) must be the same as before. In other words, event B does not affect A, and vice versa.

For part (a), we have P(B) = 1/4 and P(B|A) = 1/4 showing that P(B|A) = P(B) is true, and therefore we can say the events are independent. We don't need the info that P(A) = 1/8.

------------------------

Unlike part (a), part (b) has the answer "dependent" because P(A) = 1/8 and P(A | B) = 1/3 differ in value. Event A starts off at probability 1/8, but then event B occurring means P(A) gets increased to 1/3. The prior knowledge about B changes the chances of A. The P(B) = 1/5 is unneeded.

------------------------

If A and B were independent, then,

P(A and B) = P(A)*P(B)

However,

P(A)*P(B) = (1/4)*(1/5) = 1/20

which is not the same as P(A and B) = 1/6. Therefore the two events are dependent.

------------------------

Refer back to part (a)

P(A) = 1/4 and P(A|B) = 1/4 are identical in value, so P(A|B) = P(A) which leads to the events being independent. Whether we know event B happened or not, it does not affect the outcome of event A. P(B) = 1/9 is unneeded.

In a 100-percent-reserve banking system, if a customer deposits $100 of currency into a bank, then the money supply:
Nataliya [291]

Answer:

Option D.

Step-by-step explanation:

The total stock of currency and other liquid instruments circulating in the economy of a country as of a particular time is known as money supply.

If the reserve requirements of banks is least then banks are able to loan more money, that will increases the overall supply of money in the economy.

In 100% reserve banking system, 100% amount of each depositor's funds would be required to keep by bank for immediate withdrawal on demand.

100% reserve banking system is also known as Full-reserve banking system.

It means, if a customer deposits $100 of currency into a bank with 100% reserve banking system, then the money supply remains the same.

Therefore, the correct option is D.

review the following derivation of the tangent double angle identity. the steps are not listed in the correct order. what is the
poizon [28]

The correct order of the steps used to derive the identity is a. 4,3,5,1,2.

Really talking, identification is a combination of your physical and behavioral traits that define who you are. for example, your call is part of your identity, as is the shape and color of your eyes and your fingerprint. This set of characteristics lets you be definitively and uniquely recognizable.

Identification formation and evolution are impacted by a selection of inner and external elements like society, family, cherished ones, ethnicity, race, subculture, location, possibilities, media, hobbies, looks, self-expression, and lifestyle experiences.

The quick solution is that no, you can not absolutely erase your identity in this day and age -- except the government does it for you. Legally changing your call is not too hard. Legally converting your Social protection number (SSN) is feasible as nicely, but only below positive instances.
