No. of PINs can you choose to lock cell phone.
i.

Answer to Problem 29PPS
Total number of
Explanation of Solution
Given:
Cell phone has a
Concept Used:
For selecting the personal identification number order is important so arrangement is permuration.
Calculation:
As there are
Since the digits can be repeated, there are
For fourth place, so there are
So
Conclusion:
Therefore, total number of

Answer to Problem 29PPS
Probability how unlikely can someone guess the Pin is
Explanation of Solution
Given:
Cell phone has a
Concept Used:
For selecting the personal identification number order is important so arrangement is permutation.
Calculation:
Assume, probability how unlikely someone guesses the PIN is
Probability how likely someone guesses the PIN is
After that probability how unlikely someone guesses the PIN is equal to
i.e.
As, there are
That is,
Conclusion:
Therefore, probability how unlikely can someone guess the Pin is
