(1) An even number
Total numbers = 1 to 49 (49)
Even numbers = 24
Probability = 24/49
(2) A positive number
Total numbers = 1 to 49 (49)
Positive numbers = 1 to 49 (49)
Probability = 49/49
= 1 (100%)
(3) number divisible by 10
Total numbers = 1 to 49 (49)
number divisible by 10 = 10,20,30,40 (4)
Probability = 4/49
(4) Number greater than 50
Total numbers = 1 to 49 (49)
Number greater than 50 = 0
Probability = 0/49
= 0
(5) multiples of 5 and 7
Total numbers = 1 to 49 (49)
multiples of 5 and 7 = 35 (1)
Probability = 1/49
