Answer:

C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.

Explanation:

The main method in this code will case an error when trying to run the following line of code...

leagueName=newPlayers.getLeague();

This is because the method getLeague() is being called on a Player object which takes all of its methods from the Player class. Since getLeague() is not a method located in the player class then it cannot be called by an object from that class. Especially since the Player class does not extend to the SoccerPlayers class where the getLeague() method is actually located. Instead, it is the SoccerPlayers class which extends the Players class as its parent class.

A personal identification number (PIN) that opens a certain lock consists of a sequence of 3 different digits from 0 through 9,

Elan Coil [88]

Answer:

<u>720</u> possible PIN can be generated.

Explanation:

To calculate different number of orders of digits to create password and PIN, we calculate permutation.

Permutation is a term that means the number of methods or ways in which different numbers, alphabets, characters and objects can arranged or organized. To calculate the permutation following formula will be used:

nPr = n!/(n-r)!

there P is permutation, n is number of digits that need to be organize, r is the size of subset (Number of digits a password contains)

So in question we need to calculate

P=?

where

n= 10 (0-9 means total 10 digits)

r= 3 (PIN Consist of three digits)

So by using formula

10P3 = 10!/(10-3)!

=10!/7!

= 10x9x8x7!/7!

= 10x9x8

= 720
