Use the Midpoint for the Horizontal axis.Provide an appropriate response. 6) The table lists the smoking habits of a group of college students.Sex Non-smoker Regular Smoker Heavy Smoker Total Man 135 34 5 174 Woman 187 21 10 218 Total 322 55 15 392 If a student is chosen at random, find the probability of getting someone who is a man or a non-smoker. Round your answer to three decimal places.7) Find the probability of getting four consecutive aces when four cards are drawn without replacement from a standard deck of 52 playing cards.2Decide if the situation involves permutations, combinations, or neither. Explain your reasoning. 8) The number of 5-digit pin codes if no digit can be repeatedProvide an appropriate response. 9) How many different permutations of the letters in the word PROBABILITY are there?10) Assume that male and female births are equally likely and that the birth of any child does not affect the probability of the gender of any other children. Find the probability of at most three boys in ten births.311)Find the area of the indicated region under the standard normal curve.Provide an appropriate response. Use the Standard Normal Table to find the probability. 12) Assume that the heights of women are normally distributed with a mean of 63.6 inches and a standarddeviation of 2.5 inches. The U.S. Army requires that the heights of women be between 58 and 80 inches. If 200 women want to enlist in the U.S. Army, how many would you expect to meet the height requirements?
