STATISTIC AND PROBABILITY

Solve the following problems. Tables and graphs should be presented if needed.

1. In a dice game, one fair die is used. The player wins P24.00 if he rolls either a 1 or 6. He losses P6.00 if he turns up any other face. What is the expected winning for one roll of die? 2. An um contains four black balls and eight white balls. What is the probability of getting one black ball and one white ball in two consecutive draws from the um without replacement? 3. On a bookshelf there are 10 different Algebra books, 6 different Geometry books and 4 different Calculus books. In how many ways can you choose 3 books, one of each kind? 4. A day's production of 850 manufactured parts contains 50 parts that do not meet customer requirements. Two parts are selected randomly without replacement from the batch. What is the probability that the second part is defective given that the first part is defective? 5. A lot of 100 semiconductor chips contains 20 that are defective. Two are selected randomly, without replacement, from the lot. What is the probability that both are defective
