Probability 2 Recall: Outcome Event If all outcomes are equally likely

... In two independent experiments, the probability of getting a particular outcome in the first and a particular outcome in the second is the product of the two probabilities. Event A in first experiment has probability Pr(A). Event B in second experiment has probability Pr(B). Pr(A and B) = Pr(A)*Pr(B ...

Odds and Conditional Probabilities

... The event of a negative test given that a person does have the disease has odds 10 to 48, so the probability is 10/58 = 0.17. This is the probability of a “false negative” or in other words, it is the probability of falsely declaring that the person does not have the disease. ...

... If any event is assigned a probability, that probability must satisfy the axioms. Example: Coin tossing Suppose you toss a coin. One possible event is “heads”, another is “tails” If you assign a probability p to “heads” and a probability q to “tails they both must be between 0 and 1. As “heads” cann ...

theoretical probability

... The odds against a spinner landing on red are 2:3. What is the probability of the spinner landing on red? The odds against landing on red are 2:3, so the odds in favor are 3:2. This means there are 3 favorable outcomes and 2 unfavorable outcomes for a total of 5 possible outcomes. ...

... 2. Decimal odds (common in Europe). Decimal odds are expressed by a number (always greater than 1) which express the amount the betting house will pay for a winning bet of $1. For example decimal odds of 6 means that for a winning bet of $10 the player will get $60 back for a profit of $50. That is ...
