Two fair dice are rolled. Let A be the event the sum is even and B be the event at least one of the numbers rolled is three. (a) What is the sample space? (b) Display the outcomes in a Karnaugh map in terms of events A and B. (c) Determine P(AB).
6. Two dice are rolled, and the events F and T are as follows: F={The sum of the dice is four} and T={At least one die shows a three} Find P(F∪T). 7. The probability that this weekend will be cold is .6, the probability that it will be rainy is .7, and probability that it will be both cold and rainy is .5. What is the probability that it will be neither cold nor rainy? 8. Suppose a jar contains...
1. Two dice are thrown. Let E be the event that the sum of the dice is odd, let F be the event that at least one of the dice lands on 1, and let G be the event that the sum is 5 . List the outcomes ina. E ∩ Fb. E ∪ Fc. E ∩ F'd. E ∩ F ∩ G
1. Consider the experiment of rolling a pair of dice values showing on the dice. experiment of rolling a pair of dice. Suppose we are interested in the sum of face a. How many simple events are possible? b. List the sample space. c. What is the probability of obtaining a 7? d. What is the probability of obtaining a value of 9 or more? Because each roll has six possible even values (2.4,6,8,10,12) and five possible odd values (3,5,7,9,11),...
1. Roll a pair of dice, one red and one green. Now, define the following events: A is the event that at least one of the dice will be an even number B is the event that the sum of the die will be equal to 7; C is the event that at least one of the dice is equal to 1 (a) Draw a picture of the sample space. (b) List all the outcomes for each of the events...
am#2 Two dice are tossed once. Compute the following probabilities. 1) a. The toss results in a sum of 9 or 6 b. The toss results in sum of 18. c. The sum is less than 7 and even.
1. Toss two fair dice and let E1 denote the event that the sum is 10 and E2 the event that the first is 3. Show that the two events are not independent. Construct two independent events. Construct 4 events that are not independent but such that they are pairwise independent. 1. Toss two fair dice and let E1 denote the event that the sum is 10 and E2 the event that the first is 3. Show that the two...
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.
4. Eight rooks are placed randomly on a chess board. What is the probability that none of the rooks can capture any of the other rooks? (In non-chess terms: Randomly pick 8 unit squares from an 8 x 8 square grid. What is the probability that no two squares share a row or a column?) Hint: How many choices do you have to place rooks in the first row? After you have made your choice, how many choices do you...
