The following table displays a frequency distribution for the number of crew members on each shuttle mission from April 12, 1981 to July 8, 2011.   Let C = Crew Size a) How many shuttle missions were there from April 12th, 1981 to July 8, 2011? b) Create a probability distribution for the random variable C C = c  P(C = c) 2 0.0148 4 0.2963 5 0.0370 6 0.0444 7 0.0518 8 0.5296   1.0000 Use your probability distribution to find: c) P(C = 6) = d) P(C is at least 4) = e) P(C is no more than 7) = f) P (4 ≤ C ≤ 7) = g) P (2 < C ≤ 5) = h) What is the expected crew size? E(C) =

The following table shows 120 patients classified according to their blood sugar levels and gender. A patient is selected at random from the 120 patients. The probability that the patient selected is a male or has a normal blood sugar level is: Gender Male (M) Female (F) 40 Blood sugar level Low (L) Normal (N) High ( H) 20 30 10 15 O 0.25 ()0.7083 0.6667 0.2917

The data represent the number of driving fatalities for a certain area by age for male and female drivers.     Male Female   under 16 161 145   16-20 5900 2497   21-34 11,431 4029   35-54 12,838 5410   55-69 4898 1569   70 and over 3267 1251   ​(a) What is the probability that a randomly selected driver fatality who was female was 16 to 20 years​ old?   The probability that a randomly selected driver fatality who was female was 16 to 20 years old is approximately nothing. ​(Round to three decimal places as​ needed.)   ​(b) What is the probability that a randomly selected driver fatality who was 16 to 20 was female​?   The probability that a randomly selected driver fatality who was 16 to 20 was female is approximately nothing. ​(Round to three decimal places as​ needed.)

The following table shows the distribution of murders by type of weapon for murder cases in a particular country over the past 12 years. Complete parts (a) through (e). Probability Weapon Handgun 0.472 Rifle 0.024 Shotgun Unknown firearm 0.034 0.144 Knives 0.133 Hands, fists, etc. 0.055 Other 0.138 ... O A. If 1000 murders were randomly selected, we would expect about 58 of them to have resulted from a rifle or shotgun. O B. If 1000 murders were randomly selected, exactly of them would have resulted from a rifle or shotgun. (c) What is the probability that a randomly selected murder resulted from a handgun, rifle, or shotgun? P(handgun, rifle, or shotgun) = 0.530 (Type a decimal rounded to three decimal places as needed.) Interpret this probability. Select the correct choice below and fill in the answer box to complete your choice. A. If 1000 murders were randomly selected, we would expect about 530 of them to have resulted from a handgun, rifle, or shotgun. B. If 1000 murders were…
