Answer #1

Solution:

Yes, My friend is right because both of the envolope has equal chances to choose.

P(To choose envolope with a amount) = 1/2

P(To choose envolope with b amount) = 1/2

Now if i choose envelope with a amount than probability is 1/2. Now i can choose the switch envelopes after watching it or not so its probability is also 1/2.

So the Probability of getting b amount = 1/2 * 1/2 = 1/4

So total probability of getting b amount envelope = 1/2(in one chance) + 1/4(In second chance)

Total probability = 0.75

SO my friend is right that probability increase from 1/2 to 3/4. or 0.5 to 0.75

    Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer file....

    Exercise 2 Separation of a Mixture Based on Acid-Base Properties One purpose of this exercise is to learn how to use a separatory funnel to extract a single component away from other compounds in solution. To do so, we will apply the principles of solubility and acid-base behavior you’re seeing in class. One of the compounds is neutral in the acid-base sense. It has no ability to either donate or accept a proton from an aqueous solution, and will remain...
