Probability of the Union of Two Sets Conceptual Overview: Explore how the probability of the union of two events equals the probability that either event occurs. The two circles shown below represent two events, A and B. The area of each circle represents the probability of the event. With no overlap you can see that the probability of one or the other of the two events (the union of A and B) written as P(A U B) is the sum of their probabilities. The union is often described as an "OR" statement. The union is the probability of A occurring OR B occurring OR both A and B occurring simultaneously (their intersection). Drag one of the circles so that the circles begin to overlap. You will see that the probability of the union decreases because some probability is included in both sets (their intersection). You can also drag the letter for each set to change its size and thus its probability. P(A) = 0.129, P(B) = 0.067, P(A U B) = 0.195 B

Please do not give solution in image format thanku (Probability) Suppose that you are a merchant selling diamonds. You have three types of jewelry to sell: costume, average quality, and luxury. Costume jewelry sells for $20 per piece, average quality jewelry for $100 per piece, and luxury jewelry for $1000 per piece. Suppose, based on previous monthly sales, you expect to sell 100 pieces of costume jewelry, 30 pieces of average quality jewelry, and 5 pieces of luxury jewelry. What is expected sales this month from selling jewelry?
