Answer:
Step-by-step explanation:
An integer between 1 and 100 may be chosen in 98 ways.
Sample space or Total no. of possible outcomes = 98
1) let A be the event that no. chosen is divisible by 8. The favourable outcomes are
8,16,24,32,40,48,56,64,72,80,88,96
Favourable no. Of outcomes are=12
Hence,probability that no. Is divisible by 8 = no. Of favourable outcomes/total no. Of outcomes
P(A) = 12/98=6/49
