A box contains 600 envelopes, of which 50 contain $100 in cash, 250 contain $25, and 300 contain $10. An envelope may be purchased for $25. What is the sample space for the different amounts of money? Assign probabilities to the sample points and then find the probability that the first envelope purchased contains less than $100. Find the sample space and the weights of the sample points. Select the correct answer below and fill in the answer boxes to complete your choice. (Type integers or simplified fractions.) O A. S = (-$15, $0, $25) with weights , and respectively OB. S = ($10, $25) with weights respectively C. S = {$10, $25, $100) with weights respectively D. S = {$25, $100) with weights respectively and and + and
