Answer:
13/90
Step-by-step explanation:
The multiples of 7 that are two digit numbers = 14, 21, 28, 35, 42, 49, 56, 63, 70, 77, 84, 91, 98
Total number of two digit numbers = 90
The probability that the chosen number is a multiple of 7 = Total number of multiples of 7 that are two digit numbers / Total number of two digit numbers
The probability that the chosen number is a multiple of 7 = 13/90
