Tim Horton’s Roll up the Rim cups have a 1 in 6 chance of winning a prize. If you buy 50 cups what is the probability that: a) You will win no prize b) You will win exactly 1 prize c) You will four or fewer prizes. (Assume there are enough cups in the world that the probability of winning is independent on past cups.)

At a walk-in clinic, assume that on average exactly 6.00 patients arrive per hour, that this is true regardless of the day and the hour of the day, and that it is independent of how many patients have already arrived that hour. e) It is now 10:00 AM. A patient arrived 9:45 AM (15 minutes ago), and no other patient has arrived since then. What is the probability that the next patient will arrive before 10:30 AM?

Many track runners believe that they have a better chance of winning if they start in the inside lane that is closest to the field. For the data below, the lane closest to the field is Lane 1, the next lane is Lane 2, and so on until the outermost lane, Lane 6. The table displays the starting positions for the winners of 240 competitions. Calculate the chi-square test statistic X2 used to test the claim that the probability of...

1. We roll two fair 6-sided dice. Compute the probabilities of the following events. (a) The sum is at most 6. (b) The sum is more than 6. (c) The sum is at most 6 and at least one die is a 4. 2. Consider the letters a,b,c. Suppose we draw 2 of the letters at random (allowing for repetition). Assume order matters. That is, ab is not the same as ba: Let A : The 2 letters are distinct....

6. Figure 1 shows an example variation of congestion window for TCP Reno. Assume that TCP segment size is 1500 bytes and average RTT is 150 msec. i) What is the average throughput (in bits/sec) during transmission rounds starting from round 6 until round 10 starts. ii) What are the values of ssthresh at the 18th and 24th transmission rounds? iii) Suppose TCP Tahoe is used (instead of TCP Reno), and there is a timeout event at 22nd round. How...

Need help with well-explained solution 1. Assume that there are two urns. The first urn contains 4 red balls, 3 blue balls, and 3 white balls. The second urn contains 2 red balls, 4 blue balls, and 4 white balls. You randomly select an urn and take two balls from the urn. The probability that you pick the first urn is 40%. What is the probability that (a) the two balls are red? (b) the second ball is blue? (c)...

Problem 4 The average air speed of an F-22 and F-15E fighter jets are 2778.3 km/h and 3087 km/h, respectively. The F-22 and F-15E jets have standard deviations of 400.75 km/h and 495.45 km/h, respectively. The air force is planning on inspecting 20 of eadch variant of aircraft.
