A FIVE DIGIT NUMBER IS FORMED BY USING THE DIGITS 1,2,3,4,5 WITH OUT REPETITIONS . WHAT IS THE PROBABILITY THE NUMBER IS DIVISIBLE BY5? Select the correct option:
A) 12/15  B) 5/6  C) 4/5  D) 7/3  E) 2/7
If a number is divisible by 5 the last 1 digits of the number has 5.   If the number ends with 15: Number of possibilities = 4*3 * 2 * 1= 
<gadget id="calculator">4*3 * 2 * 1</gadget>
<output>24</output>
24   number ends with 25: Possibilities= 4*3 * 2 * 1= 
<gadget id="calculator">4*3 * 2 * 1</gadget>
<output>24</output>
24   number ends with 35: Possibilities=24   number ends with 45: Possibilities =24   Total number of possibilities with restriction = 24*4= 
<gadget id="calculator">24*4</gadget>
<output>96</output>
96   Total number of possibilities without restriction= 5! = 120   Probability = 96/120 = 12/15   12/15nswer: 12/15
