Here we want to find the probability of that we will not lose money if we purchased first envelope.
The price of the envelope = 25 Euros.
Total number of envelopes = 500
Total number of envelopes which contain 25 Euros or more than 25 Euros = 75 + 150 = 225
So the required probability = 225/500 = 450/1000 = 0.45
So final answer is = 0.45

A box contains ten sealed envelopes numbered 1,..., 10. The first six contain no money, the next two each contains $5, and there is a $10 bill in each of the last two. A sample of size 3 is selected with replacement (so we have a random sample), and you get the largest amount in any of the envelopes selected. If X, X, and X, denote the amounts in the selected envelopes, the statistic of interest is M = the...

we have four boxes. box #1 contains 2000 components of which 100 are defective. Box #2 contains 500 components of which 200 are defective. boxes #3 and #4 each contain 1000 components with 100 of them being defective. a box is selected by ruling a fair four sided die and then a single item is randomly chosen from the box. a.What is the probability that the selected component is defective? b. if the selected item is defective, find the probability...
Question 29 (4 points) Two boxes each contain five numbered balls: • Box 1 contains balls with numbers 3, 3, 3, 4, 5 • Box 2 contains balls with numbers 1, 1, 2, 2, 2 (a) You will randomly select one ball from each box. Let X be the difference between the numbers selected from the first and second box. Find the probability distribution of X. You can simply list the probabilities for each possible value of X instead of...
