Consider events A, B, C, D, E o f the sample space S = { n : n is an integer such th a t 10 ≤ n ≤ 20} given by :
A is the set of all even numbers.
B is the set of all prime numbers.
C=(15).
D is the set of all integers ≤ 16
E is the set of all double digit numbers expressible as a power of 2.

Consider events A, B, C, D, E o f the sample space S = { n : n is an i...
Since the sample space S = {n : n is an integer such that 10 < n="" />< 20},="" we="" can="" write="" it="" as="" s="{11," 12,="" 13,="" 14,="" 15,="" 16,="" 17,="" 18,="" />

Event A: The number is even. A = {12, 14, 16, 18}

Event B: The number is divisible by 3. B = {12, 15, 18}

Event C: The number is prime. C = {11, 13, 17, 19}

Event D: The number is greater than 15. D = {16, 17, 18, 19}

Event E: The number is a multiple of 5. E = {15}

Now we can determine the following probabilities:

P(A) = number of outcomes in A / total number of outcomes = 4/9

P(B) = number of outcomes in B / total number of outcomes = 3/9 = 1/3

P(C) = number of outcomes in C / total number of outcomes = 4/9

P(D) = number of outcomes in D / total number of outcomes = 4/9

P(E) = number of outcomes in E / total number of outcomes = 1/9
