The probability that a song was rock is 0.5, the probability that it had over 1,000 plays is 0.4, and the probability that it was rock or had over 1,000 plays is 0.8. What is the probability that a randomly chosen song was rock and had over 1,000 plays?
A car dealership sells two types of cars: sedans and SUVs. The dealership conducted a survey and found that out of 200 customers, 120 purchased sedans, 80 purchased SUVs, and 40 purchased both types of cars. Calculate the probability that a randomly selected customer purchased either a sedan or an SUV.
Suppose that X, Y, and Z are jointly distributed random variables, that is, they are defined on the same sample space. Suppose that we also have the following. E(X)=-1 E(Y) = 4 E (Z)=0 Var(X)=20 Var(Y) = 27 Var (Z) = 38 Compute the values of the expressions below. E (5Z-2) = 0 2Z+X -5 Var(2X-3) = 0 E = E (32²) = 0 Explanation Check X O hp Ⓒ2022 McGraw Hill LLC. All Rights Reserved. Term
Out of a sample of 10,000 men, the probability that a man picked at random weighs over 190 pounds is 0.25. The probability that a man weighs less than 135 pounds is 0.15. What is the probability that a man picked at random weighs either 190 pounds or under 135 pounds?
A group of people were asked if they had run a red light in the last year. 470 responded "yes", and 283 responded "no".Find the probability that if a person is chosen at random, they have run a red light in the last year.
A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?
A researcher is selecting lab rats for her experiment. She assigns each rat a number and picks numbers out of a hat while blindfolded. The pool of rats from which she is drawing participants is composed of the following: 23 male albino rats 21 male spotted rats 35 female albino rats 11 female spotted rats If she reaches into the hat once, what is the probability of choosing a female rat or an albino rat? Give your answer as a decimal rounded to 4 decimal places.

In order to attract customers, a grocery store started a "SAVE" game. Any person who collects all four letters of the word save gets a prize. A diligent Mrs. Reyes has three letters "s", "a" and "e" keeps going to the store until she gets the 4th letter "v". The probability that she gets the letter "v" on any visit is 0.002 and remains the same from visit to visit. Find the probability that she will not have to visit more than three times. a.0.006 b.0.004 c.0.003 d.0.007
