If values of a,b,c is given from the set {1,2,3} where a not equal to b not equal to c, then the probability that b2-4ac>0 is what?
Dear Student,
as a is not equal to b and b is not equal to c.
So we can select a,b,c from set of {1,2,3} such that numbers are not repeated.
So this can be done in 3! ways.
This is the total sample size= 6.
Now to satisfy b2 -4ac>0
Take b=3, a=1,c=2
