I need assistance with these few Math problems,

1.) Part 1 and 2?

Computer purchases: Out of 793 large purchases made at a computer retailer, 338 were personal computers, 399 were laptop computers, and 56 were printers. As a part of an audit, one purchase record is sampled at random. Round the answers to four decimal places, as needed. (a) 1What is the probability that it is a printer? {b} what is the probability that it is not a personal computer? (a) 1What is the probability that it is a printer? The probability that it is a printer is D . (b) what is the probability that it is not a personal computer? The probability that it is not a personal computer is D. How are your grades? In a recent semester at a local university, 600 students enrolled in both Statistics I and Psychology I. Of these students, 83 got an A in statistics, 78 got an A in psychology, and 36 got an A in both statistics and psychology. Round the answers to four decimal places, as needed. Part 1 of 2 (a) Find the probability that a randomly chosen student got an A in statistics or psychology or both. The probability that a randomly chosen student got an A in statistics or psychology or both is Part 2 of 2 (b) Find the probability that a randomly chosen student did not get an A in statistics. The probability that a randomly chosen student did not get an A in statistics isFlawed parts: On a certain day, a foundry manufactured 365 cast aluminum parts. Some of these had major flaws, some had minor flaws, and some had both major and minor flaws. The following table represents the results. Minor Flaw No Minor Flaw Major Flaw 16 37 No Major Flaw 79 433 Send data to Excel (a) Find the probability that a randomly chosen part has a major flaw. (b) Find the probability that a randomly chosen part has a minor flaw. (c) Find the probability that a randomly chosen part has a flaw (major or minor). (d) Find the probability that a randomly chosen part has no major flaw. Part 1 of 4 (a) Find the probability that a randomly chosen part has a major flaw. Round your answer to four decimal places. P(Major flaw) =Part 2 of 4 (b) Find the probability that a randomly chosen part has a minor flaw. Round your answer to four decimal places. P(Minor flaw) = Part 3 of 4 (c) Find the probability that a randomly chosen part has a flaw (major or minor). Round your answer to four decimal places. P(Major flaw or Minor flaw) = Part 4 of 4 (d) Find the probability that a randomly chosen part has no major flaw. Round your answer to four decimal places. P(No major flaw) =Let A, B, and C be independent events with P (A) =0.5, P (B) =0.6, and P (C) = 0.2. Find P (A and Band C). P ( A and B and C) = X 5A fair 6sided die is rolled five times. What is the probability that all five rolls are 2? Write your answer as a fraction or a decimal, rounded to four decimal places. The probability that all five rolls are 2 is D
