Answer
(A) Since the replacement is not allowed, which means that there will be different probability for each ticket selection. Therefore, the probability of success is different for each trial as the selection is done without replacement.
So, option C is correct because the probability of success is not same for each trial
(B) Success is the number of matches on the ticket number and the 7 balls number selected randomly and failure is when 7 ticket does not matches the ball number.
So, success is option B

Problem #4: (10 points) In a state lottery, the player picks 6 numbers from a sequence of 1 through 51. At a lottery drawing, 6 balls are drawn at random from a box containing 51 balls, numbered 1 through 51. Find the following. (a) Probability the player matches exactly 5 numbers (b) Probability the player matches all 6 numbers (i.e. wins the lottery!)

8. In a lottery, 6 balls are drawn randomly from a set of 49 balls numbered 1, 2, . . . , 49. You choose 6 numbers on your ticket, and you win if you have the same 6 numbers as the numbers of the balls that are drawn. It does not matter if your numbers are in the same order as the order the balls are drawn (order does NOT matter). We consider two different lottery rules in the...

Q3: TRUE OR FALSE You roll three fair dice -- one with seven sides (numbered 1 to 7), one with eight sides (numbered 1 to 8), and one with nine sides (numbered 1 to 9). X = number of dice showing odd numbers facing up. i)There are a fixed number of trials, n. 2)Each trial can be categorized as being either a success or a failure (two outcomes), and X counts the number of successes. 3)The probability of success p...

In a state lottery, a player must choose 8 of the numbers from 1 to 40. The lottery commission then performs an experiment that selects 8 of these 40 numbers at random. A player has one ticket. What is the probability that the player has (a) all 8 of the number selected? (b) seven of the 8 numbers selected? (c) at least 6 of the 8 numbers selected?

ial Expériments and Binomial Distributions A binomial experiment is a probability experiment with a number of repeated trials and the following properties: . Each trial has two outcomes. . The outcomes of each trial are independent of other trials. . The probability of each specific outcome is uniform across tr Example 1: We roll a standard 6-sided die three times. Each time we roll the die, we record whether the die landed on a number less than 5, or not....

1. In a box there are three numbered tickets. The numbers are 0, 1 and 2. You have to select (blindfolded) two tickets one after the other, without replacement. Define the random variable X as the number on the first ticket and the random variable Y as the sum of the numbers on your selected two tickets. E.g. if you selected first the 2 and second time the 1 , then X = 2 and Y-1 +2 = 3. a./...
