I picked an integer from 1 to 50. What is the probablity that the number I picked is:

(a) 33?

(b) 57?

(c) odd?

(d) a multiple of 7?

Solution

a. 1/50 = 0.02

b. 0 . since there is no 57 in the numbers from 1 to 50.

c. 25/50 = 1/2 = 0.5 . since there are 25 odd numbers between 1 and 50.

d. 7/ 50 = 0.14 since there 7 numbers which are multiples of 7 from 1 to 50.
