Explanation:
S=(1,2,3,4,5,6,7,8,9,10,11,12,13 till 60)
n(S)=60
Event A: bears a two digit number
A= (14,21,28,35,42,49,56)
n(A)=7
P(A)=n(A)/n(S)=7/60

Answer:
7/60
Explanation:
Total no of probability=60
probability of number multiple by 7 is=(14,21,28,35,42,49,56)
probability = total number of outcome/favorable number of outcome
=7/60
therefore the probability that it bears a two digit number multiple of 7 is 7/60
