What is the frequency of an event? this is for forensic science

Probability

Explanation:

Probability refers to the frequency of an event, that is, it associates numbers with the chances of a particular event happening, so that the higher this number, the greater the chance of this result occurring. Probability is the study of experiments that, even if performed under very similar conditions, have results that are not possible to predict. For example, the heads or tails experiment, even if repeated over and over, cannot be predicted, because each time the coin is thrown, the result may differ.

after lydia compare her check register to her bank statement, and the ending balances do not seem to match. then, she must make a bank reconciliation by putting the data all together.

to do this, she need to determine the bank ending balance. after, add the deposits in transit then deduct the outstanding checks. moreover, if the actual checkbook balance does not equal this number, check again for transporting errors by subtracting the balances and add the difference to nine. sometimes, a mathematical error can happen but a bank reconciliation is a great tool to resolve the discrepancies.
