Three - digit numbers formed by using digits 0, 1, 2 and 5 (without repetition) are written on different slips with
distinct number on each slip, and put in a bowl. One slip is drawn at random from the bowl. The probability that the
slip bears a number divisible by 5 is??

12 three digit numbers can be formed without repetition from the given numbers[0,1,2,5]
{since zero cannot come in hundred's place
if zero is fixed in tens place 6 numbers can be formed and
if zero is fixed in ones place 6 numbers can be formed
therfore totally 12}
out of this 12 numbers formed , 4 numbers are divisible by 5[ that is ending with 5]
therefore,probability of obtaining a number divisible by 5 is 4/12=1/3
