### how do i find the probability for questions like this? A

Probability is the maths of chance. A probability is a number that tells you how likely (probable) something is to happen. Probabilities can be written as fractions, decimals or percentages One hundred of the students are chosen at random and are given the revision module. Out of these, 90% of the high achievers pass the test and 20% of the low achievers also pass. Based on these results, if a student chosen at random, takes the module, and passes it, what is the probability that he or she is a high achiever The odds, or chance, of something happening depends on the probability. Probability represents the likelihood of an event occurring for a fraction of the number of times you test the outcome. The odds take the probability of an event occurring and divide it by the probability of the event not occurring The probability that a student in a class will pass maths test is 3/5 how many student are likely to pass math Get the answers you need, now! lymprick lymprick 07.07.2020 Math Primary Schoo

Answers and Explanations. 1. B: On a six-sided die, the probability of throwing any number is 1 in 6. The probability of throwing a 3 or a 4 is double that, or 2 in 6. This can be simplified by dividing both 2 and 6 by 2.

### Multiple Choice Test: Binomial Probabilit

Akili has two tests next week. The probability that he will pass the first test, science, is 34 . How he does on that test affects how he will do on his math test. If he passes science, then the probability that he will also pass the math test is 45; otherwise, the probability is only 13 that he will pass the math test 34) The students of a particular class were given two tests for evaluation. Twenty-five percent of the class cleared both the tests and forty-five percent of the students were able to clear the first test. Calculate the percentage of students who passed the second test given that they were also able to pass the first test Thus, using Bayes Theorem, there is a 7.8% probability that the screening test will be positive in patients free of disease, which is the false positive fraction of the test.

David became interested in probability in high school while attending the 1988 (and 1989) Hampshire College Summer Studies in Mathematics. He graduated from Harvard in 1996, majoring in mathematics, received his Ph.D. from Cornell in 2002, also in mathematics, and spent three years as a postdoc at the University of California, Berkeley, in the department of statistics Principles of Probability. The mathematics field of probability has its own rules, definitions, and laws, which you can use to find the probability of outcomes, events, or combinations of outcomes and events. To determine probability, you need to add or subtract, multiply or divide the probabilities of the original outcomes and events admission pass the exam.
