dice game works like this: If you roll a 1, 2 or 5, you lose $60. If you roll a 3, you win $300. If you roll a 4 or 6, you win $20. Should you play the game? Answer yes or no. __________ Use expected values and decision theory to justify your answer. Please round the answer to two decimal places. Expected value of four games is $__________.

A research center poll showed that 83% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief? The probability that someone does not believe that it is morally wrong to not report all income on tax returns is. (Type an integer or a decimal.)

A student takes a 40-question multiple-choice exam but did not study and randomly guesses each answer. Each question has three possible choices for the answer. Find the probability that the student guesses more than 75% of the questions correctly. (Round your answer to three decimal places.) ch4#4

SITY Suppose the boxplot below depicts the daily sales (in KD) for a sample of 260 days for a given retail store. A Note that: • B= 868 KD ● C= 1028 KD D = 1188 KD ● Questions: B - The distribution of the data is symmetric - The data depicted in the boxplot includes - How many days had sales above 1188 KD? D - What percentage of days had sales above 868 KD? KD + - What is the interquartile range (IQR) for this data? IQR = - What is the value of point E? days E * days % - The number of days that had sales between 868 KD and 1188 KD is days

Probability of the Union of Two Sets Conceptual Overview: Explore how the probability of the union of two events equals the probability that either event occurs. The two circles shown below represent two events, A and B. The area of each circle represents the probability of the event. With no overlap you can see that the probability of one or the other of the two events (the union of A and B) written as P(A U B) is the sum of their probabilities. The union is often described as an "OR" statement. The union is the probability of A occurring OR B occurring OR both A and B occurring simultaneously (their intersection). Drag one of the circles so that the circles begin to overlap. You will see that the probability of the union decreases because some probability is included in both sets (their intersection). You can also drag the letter for each set to change its size and thus its probability. P(A) = 0.129, P(B) = 0.067, P(A U B) = 0.195 B
