A combo meal at Bayes' Burgers comes with fries, a burger, and a soda. The fries can be small, medium, or large, and the soda can be diet or regular. A fry cook makes the observation that 80% of the customers who choose the small fry in their combo choose a regular soda. While 60% of the customers who choose a large fry in their combo choose a diet soda. And 99% of customers who chąose the medium fry in their combo choose the regular soda. Assume 25% of customers choose a small fry in their combo, and 35% choose the large fry. If a customer chose the diet soda, what is the probability they chose the small fry?

- In a cooking competition called Heaven's Kitchen, two teams compete against each other to serve a restaurant full of customers. The competitors cook dishes and send them to an executive chef, where it is either approved and sent to the customer, or is deemed unacceptable and sent back to the kitchen. The competition has run for the past 19 years. During the 9th annual Heaven's Kitchen competition, the Ruby team cooked a total of 124 dishes, of which 50 were sent back to the kitchen by the executive chef. In the same period, the competing Sapphire team cooked a total of 154 dishes and had 56 return. Construct a confidence interval to estimate the difference in the proportion of dishes sent back to the Ruby team and the proportion of dishes sent back to the Sapphire team. Use a confidence level of 93%. Round each answer to 4 decimal places. Do not round from one part to the next when performing the calculations, though. Find the confidence interval. <p1−p2<StarHortons Cup, the coffee company, wants to determine how long caffeine lasts throughout the day when individuals have a cup of one of their 3 types of coffee at 9am.

Customers select the merchandise they want to purchase, then at the cash register they spin a wheel to determine the size of the discount they will receive. The wheel is divided into 12 regions, like a clock. Six of those regions are red, and award a 10% discount. The three white regions award a 20% discount and two blue regions a 40% discount. The remaining region is gold, and a customer whose lucky spin lands there gets a 100% discount - the merchandise is free! Determine each of the probabilities.

- Joe and Maggie take turns mowing the lawn each week. Maggie suggests they try a new system for determining who should mow the lawn. Each week, they will roll two dice and determine the sum of the values. Since the highest possible sum is 12, Maggie will mow the lawn if the sum is 6 or less, and Joe will mow the lawn if the sum is greater than 6. Before agreeing to Maggie's suggestion, Joe wants to check if this plan would be fair. He decides to roll a pair of dice and determine the sum of the values 100 times. The graph shows the results of the 100 trials. Based on his simulation, should Joe agree to Maggie’s plan? (yes/no), because a sum greater than 6 is likely to occur (more than, less then, equal to)(30%, 50%, 75%) of the timeA car wash has three different types of washes: basic, classic, and ultimate.
