Answer:
2/15
Step-by-step explanation:
Since the person is asked to say two digit number, the number has to be in between
10 and 99 (both including 10 and 99)
Total two digit number from 10 to 99=90
Two digit multiple of 7= 14, 21, 28, 35, 42, 49, 56, 63, 70, 84, 91,98 .
Total=12
P(two digit multiple of 7)= 12/90=2/15
THEREFORE, THE PROBABILITY OF THE TWO DIGIT NUMBER BEING A MULTIPLE OF SEVEN IS 2/15
