- TOPIC :PROBABILITYarrow_forwardFind the expected payback for a game in which you bet $6 on any number from 0 to 399. If your number comes up, you get $2000arrow_forwardSuppose you play a coin toss game in which you win $1 if a head appears and lose $1 if a tail appears. In the first 100 coin tosses, heads comes up 35 times and tails comes up 65 times. What percentage of times has heads come up in the first 100 tosses? What is your net gain or loss at this point?arrow_forward
- A player rolls a fair dice and gets "$3 multiplied by the value on the dice" in the case of even outcome and loses "$4 multiplied by the value on the dice" in the case of odd outcome. What's his average payout? Enter the value belowarrow_forwardThe is the belief that a string of losses in the past will be compensated by wins in the future. O winning wager O gambler's fallacy O gambler's bet O law of large numbersarrow_forwardConsider two products, A and B, both of which have the same purchase probability.Product A has a population size of 1000 and a 50 percent awareness probability. ProductB has a population size of 10,000 and a 5 percent awareness probability. Which productdo you expect to sell more?a. Product Ab. Product Bc. They are expected to sell the same amount.arrow_forward
- A magazine subscription service is having a contest in which the prize is 180000. If the company receives 3 million entries, which is the expection of the contest?arrow_forwardSC Español The owner of a chain of mini-markets wants to compare the sales performance of two of her stores, Store 1 and Store 2. Sales can vary considerably depending on the day of the week and the season of the year, so she decides to eliminate such effects by making sure to record each store's sales on the same 8 days, chosen at random. She records the sales (in dollars) for each store on these days, as shown in the table below. Day 1 2 3 4 5 6 7 8 Store 1 878 511 837 835 755 241 713 443 D Store 2 685 412 785 763 480 173 639 287 Difference (Store 1 - Store 2) 193 99 52 72 275 68 74 156 Send data to calculator V Based on these data, can the owner conclude, at the 0.05 level of significance, that the mean daily sales of the two stores differ? Answer this question by performing a hypothesis test regarding μ (which is u with a letter "d" subscript), the population mean daily sales difference between the two stores. Assume that this population of differences (Store 1 minus Store 2) is…arrow_forwardProbability as a game of chance is used to make decisions in the presence of uncertainty. It has several Industrial Applications; State any four of these applications and write briefly on one, highlighting its usefulness or benefits.arrow_forward
