A certain model car has a keypad with 5 numbers on the door. To open the door, 5 numbers must be entered in the correct
MrRissso [65]

Answer:  A. \dfrac{1}{120}

Step-by-step explanation:

Total digits on keypad = 5

According to permutation,

If repetition of digits is not allowed then the number of 5-digits passwords can be formed = 5!

= 5 x 4 x 3 x 2 x 1         [n!=n x (n-1) x (n-2)x ... x 1]

=120

The probability that someone guesses the correct code = \dfrac{\text{Number of correct codes}}{\text{Total possible codes}}

=\dfrac{1}{120}

Hence, the correct option is A.

|-3 + 15| what is the sum (answer) ? I think it is 12 but my friend thinks it is 18. Who is right?
Aliun [14]
I do believe it is 12 as well considering the fact that it's negative three and not positive. If it was a positive three then maybe it would be 18.
