How to find the probability of events a and b How to find the probability of events a or b What the probability of rolling exactly one 1, if you roll a dice 5 times? Suppose that you are given the probability, p(a) = 5/9, what are the odds in favor of a occurring? Suppose th...
It is important to read each problem carefully to think about and understand what the events are. Understanding the wording is the first very important step in solving probability problems. Reread the problem several times if necessary. Clearly identify the event of interest. Determine whether there...
Hence, the required probability = (3/7) x (3/7) x (3/7) = 27 / 343 Example 9: One bag contains 8 yellow balls and 6 black balls; another bag contains 7 yellow balls and 5 blue balls. If one ball is chosen from each bag, then what is the probability that both are yellow?
Can modal verbs refer to past events? Yes, modal verbs like could, might, should, and would can indicate past scenarios, often paired with the present perfect form of the main verb. (Example: I should have called earlier.) What are some less common modal verbs? Modal verbs like shall an...
What is probability? Describes how to interpret probability. Shows how to compute probability. Sample problems with solutions plus free, video lesson.
Financial analysts use posterior probability to analyze the interrelationships of many different types of events. Foreign exchange rates, changes in economic policies, and consumer spending habits are all examples of events that could affect stock prices. Quantifying the probabilities that these events wil...
Calculations for situations involving more than two events or variables become far more complex. Many suggest they may be simplified by using actual numbers rather than percentages or rates. Conditional probability is often the first step necessary in computing advanced functions, such as inverse probab...
