QUESTION 8 Find the probability. Each of ten tickets is marked with a different number from 1 to 10 and put in a box. If you draw a ticket from the box, what is the probability that you will draw 5, 6, or 1? 05 10 ООО 10 QUESTION 9 Find the indicated measure.

2. A box contains tickets marked 1,2,3, n. A ticket is drawn at random from the box. Then this ticket is replaced in the box and a second ticket is drawn at random. Find the probability the second number drawn is smaller than the first. (Recall 1 + 2 + 3 + + k-en! i k(k+1) ).
Two tickets are drawn from a box with 5 tickets numbered as follows: 1,1,3,3,5. If the tickets are drawn with replacement, find the probability that the first ticket is a 1 and the second ticket is a 5. If the tickets are drawn without replacement, find the probability that the first ticket is a 1 and the second ticket is a 3. If the tickets are drawn without replacement, find the probability that the first ticket is a 1 and...
(1 point) A certain senior citizen purchases 51, "6-49" lottery tickets a week, where each ticket consists of a different six-number combination. The probability that this senior will win - (to win at least three of the six numbers on the ticket must match the six-number winning combination) on any ticket is about 0.018638. What probability distribution would be appropriate for finding the probability of any individual ticket winning? Part (a) How many winning tickets can the senior expect to...
Q2] (12 Marks): Eight balls, each marked with different whole number from 2 to 9, are placed in a box. Three of balls are drawn at random (with replacement) from box. i. What is the probability that the ball with the number 5 is drawn? ii. What is the probability that the three numbers on the balls drawn are odd? What is the probability of that the sum of the three numbers on the disc is odd. iv. What is...
5. Ying has bought 50 tickets in a lottery with multiple prizes. She has checked and knows that exactly two of her tickets are winning tickets. She then put each ticket into an envelope and shuffles the envelopes before writing Willem's name on five of the envelopes. Let W be the number of winning tickets in the envelopes with Willem's name on a) What distribution could be used to model W7 Please name the distribution and give the parameter(s). State...
Part B: Sampling and Random Variable You already have ten marked pennies (ones with numbers from Part A) and 15 unmarked pennies. Thought experiment: Throw them all in a jar and shake. Without looking, pull three out and record how many of them are marked (have a number). You will get 0, 1, 2, or 3 marked coins. How many different samples of 3 pennies out of 25 can you get? (Order doesn’t matter.) Answer: 2,300 Show why 2,300 is...
Consider an urn that contains 10 tickets, labelled From this urn, I propose to draw a ticket. Let X denote the value of the ticket I draw. Determine each of the following: (a) The probability mass function of X (b) The cumulative distribution function of X (e) The expected values of X. (d) The variance of X. (e) The standard deviation of X. Note for the above TWO problems: . You are not required to include the graph of PMF...
1)The probability that an event occurs in each of 18 independent trials is 0.2. Find the probability that this event will occur at least three times? 2)The probability of winning with one purchased lottery ticket is 0.02. Evaluate the probabilities of winning a prize with n tickets for n = 1,10,20,30,40,50,60,70,80,90,100 if the tickets belong to different series for each case.
1) Three dice are rolled. If each lands on a different number, find the probability that one is 3? 2) ) Three machines (A, B, C) manufacture screws. They manufacture 25%, 35%, and 40% of the screws, respectively. The output screws are defective at 2%, 3%, and 5%, respectively. If you choose a random screw produced at the factory and it is defective, what is the probability it came from each machine A, B, and C
