thousands separator, 5 000), "E" or "e" (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker. Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values. For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not. The following data were obtained from a survey of college students. The variable X represents the number of non- assigned books read during the past six months. x 0 1 2 3 4 5 6 P ( X = x ) 0.55 0.15 0.10 0.10 0.04 0.03 0.03 Find P(1 < X < 5). Place your answer, rounded to two decimal places in the blank. For example, 0.56 would be a legitimate entry. .24
Question 13 of 20 1.0/ 1.0 Points
Accepted characters : numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation). NOTE: For scientific notation, a period MUST be used as the decimal point marker. Complex numbers should be in the form (a + bi) where "a" and "b" need to have explicitly stated values. For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not. If a gambler rolls two dice and gets a sum of four, he wins \$10; and if he gets a sum of three, he wins \$25. The cost to play the game is \$5. What is the expectation of this game? Place your answer, rounded to two decimal places , in the blank. -2.78 When entering your answer do not use a dollar sign. However, if the expected payoff is negative be sure to use a minus sign. For example, -1.23 would be a legitimate entry.

Find the mean of the following probability distribution? 1 0.20 2 0.10 3 0.35 4 0.05 5 0.30 Place your answer, rounded to two decimal places , in the blank. 3.15 When entering your answer do not use any labels or symbols other than a decimal point. Simply provide the numerical value. For example, 1.23 would be a legitimate entry.
Part 4 of 6 - 2.0/ 4.0 Points Question 15 of 20 1.0/ 1.0 Points Accepted characters : numbers, decimal point markers (period or comma), sign indicators (-), spaces (e.g., as thousands separator, 5 000), "E" or "e" (used in scientific notation).

For example: {1+1i} is valid whereas {1+i} is not. {0+9i} is valid whereas {9i} is not. If you have six books, but there is room for only four books on the shelf, in how many ways can these books be arranged on the shelf? Place your answer in the blank. Do not use any decimal places or commas. For example, 45 would be a legitimate entry. 360
