Consider the experiment of selecting a whole number starting at one and less than 20. Let event A be getting an even number and event B be getting a number greater than 13. (a) What is the sample space? (b) Find P(A) (c) Find P(B)

Ans. (a) S={ x | x is an integer & 1=<x<20 } or S={1,2,3,...,19} (b) A={ 2,4,6,8,10,12,14,16,18} =>P(A)=9/19 (c) B={14,15,16,17,18,19} =>P(B)=6/19

. [1, 20) a set of numbers from 1 that excludes the number 20. That is 19 numbers. A = { 2, 4, 6, 8, 10, 12, 14, 16, 18 } B = { 14, 15, 16, 17, 18, 19} a) Sample space = 19 b) P(A) = 9/19 c) P(B) = 6/19
