Binomial Probabilities
... (3) Assume that I sample 7 times with replacement from an urn with 2 red ball, 1 white ball and 3 blue balls. What is the probability that I drew the white ball exactly 5 times? Note that all the experiments above have the following three things in common. (1) A same experiment is repeated several t ...

... • trial 1: pick a ball – event E1 = the ball is red • do not replace the ball in the bag • trial 2: pick a ball – event E2 = the ball is red What is the probability of the event E, where E = picking two red balls on successive trials (without replacement)? In this case, the probability of E2 is affe ...

... What is Theoretical Probability? A Reminder: Experimental probabilities are calculated by performing experiments. If a die is rolled 20 times and the number 3 comes up 4 times, the experimental probability of rolling a 3 is 4/20 (1 out of 5, or 20 percent or 0.20) Theoretical probabilities are ...

... The Multiplication Law for Independence Event • Just to remind you that for independents events, one outcome is not dependent to occurrence of the next outcome. • The second basic law (multiplication law) of probability is intended for computing joint probabilities. • Pr[A and B] = Pr[A] X Pr[B] ...

However, probability does not allow us to make short-run predictions. The myth of the “law of averages”: Probability tells us random ...

Understanding Probability and Long-Term
... Applying Some Simple Probability Rules Rule 3: If two events do not influence each other, and if knowledge about one doesn’t help with knowledge of the probability of the other, the events are said to be independent of each other. If two events are independent, the probability that they both happen ...
