Question 31 Write Correct Values Boxes Question Working Required Marked Math1234 Enrolment Q28918143

Hi,

Could you please explain your working with answers.

Thanks very much!

Question 31 Write the correct values in the boxes For this question, working is not required and will not be marked MATH1234 has an enrolment of 60 students. The lecturer, Brooke Malcolm, will randoml assign 20 students to each of three tutorials A, B and C Friends Xing, Yuxi and Ziyi want to know the probability that at least one of them wil end up in tutorial A. The sample space for the experiment of Brookes choice is the set S of all possible class lists (unordered) for Tutorial A, and the event E of interest is that the outcome of the experiment has non-empty intersection with {X, Y, Z) With the help of WolframAlpha, or some similar computaional aide, for each of the items below find the 2-digit (natural) number that provides the best approximation (a) SI x 1014 × 1014. (c) P(E)~| | % The remaining questions may require more thought and may require the use of some probability rules Using similar methods to those used above find the probabilities below, again giving the 2-digit (natural) number that provides the best approximation (d) The probability that the three friends end up in the same tutorial is approximately Hint: First find the probability that they all end up in tutorial A (e) The probability that at least one of the friends ends up in tutorial A, or at least one of the friends ends up in tutorial B, (or both) is approximately% (f) [Challenge!
