Answer:

The thief has a 0.11% probability of hitting the pin code on the first try.

Explanation:

Simply, if the ATM card has a 3-digit code that can be repeated, and the board has 9 numbers (for example, from 1 to 9), we must start from the smallest number that could be formed with these numbers to the highest number that these numbers could also compose, which in the case would be 111 and 999. Then, 889 different numbers could be formed (it is the distance between 111 and 999), with which the possibility of hitting the key to the first attempt would be 1 in 889 times, or 1/889.

To take the probability to a percentage, we must know that 889 / 8.89 gives 100. Therefore, dividing 1 / 8.89 we will know the percentage of probabilities of hitting the key on the first attempt: 1 / 8.89 = 0.11.

This shows us that the thief has a 0.11% probability of hitting the key on the first try.

A credit entry:
blagie [28]

Answer: e. Decreases asset and expense accounts, and increases liability, common stock, and revenue accounts.

Explanation:

Let's evaluate each of the options as follows:

a. Is always a decrease in an account - This is false because a credit entry increases liability, common stock and revenue accounts.

b. Is recorded on the left side of a T-account - Although in modern day accounting, the use of T-account has been relegated to the background. However, if entries are to be recorded using the T-account, all debits are posted to the left side while all credits are recorded on the right side of the account.

c. Increases asset and expense accounts, and decreases liability, common stock, and revenue accounts - It does not increase asset and expense accounts, rather it reduces them. The opposite applies to liability, common stock, and revenue accounts.

d. Is always an increase in an account - This is false.

Therefore, option e is correct because a credit entry reduces asset and expense accounts, and increases liability, common stock and revenue accounts.
