Probabilities

Six students will decide which of them are on a committe by flipping a coin. Each student flips the coin and is on the committee if he or she gets a head. What is the probability that someone is on the committe, but not all 6 students?

Probability Distribution

Give a probability distribution for the following: In 1992, the Big 10 collegiate sports conference moved to have women compose at least 40% of its athletes within 5 years. Suppose they exactly achieve the 40% figure, and that 5 athletes are picked at random from Big 10 universities. The number of women is recorded. For the probability distribution, you need to figure out the probabilities of 0 through (and including) 5 women. These are your x's. Put this in the form of a table. On the left hand side, put 0 through 5. On the right hand side, give the formula for each, and calculate. From the information about exactly 40%, we know that the probability of success (of being a female athle... click for more

Finite Mathematics - 20 Review Questions

Please see the attachment. Problems 1-3 (also attached): Acme Inc. has just purchased new computers for $60,000. Suppose that in 8 years the computers will have a salvage value of $8,000. The college plans to depreciate the value of the computers linearly over the 8 years. 1. Based on the above information, value (y) is a function of time (x). Compute the values of m and b that satisfy the equation y = mx + b. a) Find m. b) Find b. 2. What will the value of the computers be 5 years from now? 3. In the context of this problem, which of the following best describes the meaning of the slope? (a) The accumulated depreciation (b) The depreciation per year (c) The val... click for more
