5 numbers chosen randomly without replacement. "B" represents number of even numbers, this random variable has this probability: x 0 1 2 3 4 5 p(B=x) 0.02693 0.15989 .33858 .31977 .13464 .02020 number of odd #s chosen would then be 5-x, if x is even #s chosen. "C" represents difference b/w # of even and # of odd chosen, --> C= 2B-5 a. probability that exactly 1 even # chosen? b. probability at most 1 even # chosen? c. prob....
6 numbers are chosen in order from the numbers 1, 2, ..., 49 a. Find the probability the numbers are drawn in **strictly** increasing order; (i.e., the first < the second < the third) if i. draws are made without replacement ii. draws are made with replacement. b. Assume the draws are made without replacement. Find the probability that the numbers form an arithmetic sequence drawn in any possible order (for example 9,3,6,12,18,15) C.Assume the draws are made with replacement....
4.26 In a lottery game, three winning numbers are chosen uniformly at random from (1, ,100), sampling without replacement. Lottery tickets cost $1 and allow a player to pick three numbers. If a player matches the three winning numbers they win the jackpot prize of $1,000. For matching exactly two numbers, they win $15. For matching exactly one number they win $3 d) Hoppe shows that the probability that a single parlayed ticket will ulti- mately win the jackpot is...
Problem 1 (35 points): Two numbers are chosen at random and simultaneously from among the numbers 1 to 4 without replacement. Let A,产(1,2,3,41, be the event that the first number is . 1. Find the probability of the event B that the second number chosen is 3. 2. What is the probability that the first number is 1 given that the second number is 3?
(5) The numbers 1,2,3,4,5, and 6 are written on slips of paper, and 2 slips are drawn at random one at a time without replacement. Find the probabilities of (a) The sum of the outcomes is 8 (b) The first number is 3 or the sum is 8. (6) Given that (xi — 7)2 = 40 i=1 Find the sample standard deviation, s

What is the probability of rolling any three even numbers on one roll of three seven sided dice?
Thirty-two people were chosen at random from employees of a large company. Their commute times (in hours) were recorded in a table (shown bellow). 0.4, 0.9, 0.3, 0.5, 0.7, 1.2, 1.1, 0.7 0.6, 0.5, 0.8, 1.1, 0.9, 0.2, 0.5, 1.0 0.9, 1.0, 0.7, 0.2, 0.6, 1.1, 0.7, 1.1 0.5, 1.3, 0.7,0.6, 1.0, 0.8, 0.5, 0.9 Construct a frequency table using a class interval width of 0.2 starting at 0.15.
