Answer:
4/25 or 0.16
Step-by-step explanation:
Total no.of events = 100
Sample space for Numbers less than 100 and divisible by 8 = [8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96]
Sample space for numbers less than 100 and divisible by 12= [12, 24, 36 .48 60, 72, 84, 96]
Sample Space for favorable events= [8, 12, 16, 24, 32, 36, 40, 48, 56, 60, 64, 72, 80, 84, 88, 96]
No. of favorable events= 16
Probablity= No. of Favorable events/ Total no. of events
=16/100
=4/25 or 0.16
