You can put this solution on YOUR website! The digits 4,5,6,7 and 8 are randomly arranged to form a three
digit number(Digits are not repeated) Find the probability that
the number is even and greater than 800.
The denominator of the probability is 5P3 = 5*4*3 = 60
The numerator is: choose the 1st digit as 8 one way, the last
digit 2 ways (4 or 6) and the middle digit any of the remaining
3 ways:
1*2*3 = 6
Answer: the probability is 6 ways out of 60 = 6/60 = 1/10
