Last week I used a stopwatch to measure the echo time of my snare drum in the hall outside my classroom, which is 80 meters long. The average echo time was 10 milliseconds. Use your understanding of the Echo Ranging formula to prove or disprove my findings, remember this echo was heard in air.
An oil drilling operation predicts the success of a new well based on the geological structure. Experience shows what the probability of a type A structure at the site of a productive well is 0.40. The company also knows that 50% of all wells are drilled in locations with type A structure. Finally, 30% of all wells drilled are p
A company sells two products (Product 1 and Product 2) that tend to be substitutes for each other. That is, if a customer buys Product 1, she tends to not buy Product 2, and vice versa. The company assessed the joint probability distribution of demand for the two products for this year. The joint distribution is shown below.
A soft drink bottling company maintains records concerning the number of unacceptable bottles of soft drink obtained from the filling and capping machines. Based on past data, the probability that a bottle came from machine I and was nonconforming is 0.05 and the probability that a bottle came from machine II and was nonconform

The oasis outpost of Abu Ilan, in the heart of the Negev desert, has a population of 20 Bedouin tribesmen and 20 Farima tribesmen. El Kamin, a nearby oasis, has a population of 32 Bedouins and 8 Farima. A lost Israeli soldier, accidentally separated from his army unit, is wandering through the desert and arrives at the edge of o
Let Qn denote the probability that in n tosses of a fair coin no run of 3 consecutive heads appears. Show that: Qn = ½ Qn-1 + ¼Qn-2 + ⅛Qn-3 Q0 = Q1 = Q2 = 1 Find Q8. HINT: Condition of the first tail. Please see attached for proper equation format.
Do Problem 2 ONLY please. Problem 1 An urn contains n+m balls, of which n are red and m are black. They are withdrawn from the urn, one at a time and without replacement. Let X be the number of red balls removed before the first black ball is chosen. Find E[X]. To obtain this quantity, number the red balls from 1 to n. Now

In an experiment, subjects are required to generate a "yes" or "no" decision. The probability of 'Yes' being correct is 50%. The observed probability of yes decisions is 70%. What is the probability that any "Yes"-outcome question will be answered correctly? Illustrate computational details of answer briefly.
