Single Maths B Probability & Statistics: Exercises & Solutions 1. QUESTION: Describe the sample space and all 16 events for a trial in which two coins are thrown and each shows either a head or a tail. SOLUTION: The sample space is S = {hh, ht, th, tt}. As this has 4 elements there are 24 = 16 subsets, namely
Practice and Problem Solving: A/B. Determine the probability of each event. Write impossible, unlikely, as likely as not, likely, or certain. Then, tell whether the probability is 0, close to 0, 1 , close to 1, or 1. 2. 1. randomly picking a blue card from a bag containing all blue cards.

Probability Questions with Solutions. Tutorial on finding the probability of an event. In what follows, S is the sample space of the experiment in question and E is the event of interest. n (S) is the number of elements in the sample space S and n (E) is the number of elements in the event E.
17 Ιουλ 2010 · Suppose X be a simple random variable. Since jX([0; 1])j < @0 < c = j[0; 1]j (where jj refers to the cardinality of the considered sets), we conclude that there is at least one y 2 X([0; 1]) such that for at least two elements w1; w2 2 [0; 1] we have X(w1) = y = X(w2), contradicting injectivity of X. Exercise 4.5.8.

The probability in part (e) represents the probability of an individual value. In part (f), the probability describes the mean of a sample of 25. Part (f) relies on the central limit theorem, so the distributions are different. Part (e) is exponential and part (f) is normal.
