a) P(sum is less than 5 or greater than 9) = P(2) + P(3) + P(4) + P(10) + P(11) + P(12) = (10 + 30 + 50 + 120 + 80 + 70) / 1000 = 360/1000 = 0.36
Odds = 360 / (1000 - 360) = 360 / 640 = 9/16
b) P(sum is even or exactly divisible by 5) = P(2) + P(4) + P(5) + P(6) + P(8) + P(10) + P(12)
= (10 + 50 + 70 + 110 + 170 + 120 + 70) / 1000
= 600/1000
= 0.6
Odds = 600 / (1000 - 600) = 600/400 = 3/2

A pair of dice are rolled 1,000 times with the following frequencies of outcomes: Sum 2 3 4 5 6 7 8 9 10 11 12 Frequency 10 30 50 70 110 150 170 140 120 80 70 Use these frequencies to calculate the approximate empirical probabilities and odds for the events a. The sum is less than 5 or greater than 8. b. The sum is even or exactly divisible by 3.

One card is drawn from an ordinary deck of 52 cards. Find the probabilities of drawing the following cards. 15. (a) A 9 or 10 (b) A red card or a 3 (c) A 9 or a black 10 (d) A heart or a...
A standard pair of six-sided dice is rolled. What is the probability of rolling a sum greater than 9? Express your answer as a fraction or a decimal number rounded to four decimal places.
In the carnival game Under-or-Over-Seven, a pair of fair dice is rolled once, and the resulting sum determines whether the player wins or loses his or her bet. For example, using method one, the player can bet $2.00 that the sum will be under 7, that is, 2, 3, 4, 5, or 6. For this bet, the player wins $2.00 if the result is under 7 and loses $2.00 if the outcome equals or is greater than 7. Similarly, using...
