A men's basket ball team assigns every player a two digit number for the back of his jersey. If the digit uses the digits 1 to 5, what is the maximum number of players that can join the league such that no player has a number with repeated digits (like 22) & no two players have the same number??

Guys, after answering the above question, kindly consider the following scenarios:

Scenario 1: What will be the answer, if the repetition (eg 22) is allowed.

Scenario 2: What will be the answer, if every player is assigned a "three" digit number from the digits 1 to 5 & the repetition of digits (eg 323 or 333) is not allowed.

Scenario 3: What will be the answer, if every player is assigned a "three" digit number from the digits 1 to 5 & the repetition of digits (eg 323 or 333) is allowed.

Well, I think if I can get some views on these scenarios, I can understand "Combinatorics". These scenarios emerged as a result of a discussion between myself & AtifS (an active member of the club & my partner).

The source of question is MGMAT Guide while the 3 scenarios are our creation. _________________

Scenario1: if repetition allowed then its 5 * 5 = 25 players.

Scenario 2: 5 * 4 * 3 = 60 players.

Nice! can you please! explain y did you take 5*5=5^2 for 1st scenario and y did you take 5*5*5=5^3 for 3rd scenario? I just wanted to know the logic behind t. Well I think 5 options are possible for 1st digit and similarly 5 for 2nd digit. Same goes for 3-digit number. But would like to know your explanation as there might be anything useful to know Thanks,

The logic is same as you said, if digit repeat is allowed than ways to select 1st digit = 5 (either of 1,2,3,4,5) ways to select 2nd digit = 5 (either of 1,2,3,4,5) total = 5*5 = 25

for the case when number on player's shirt is of three digits then ways to select 1st digit = 5 (either of 1,2,3,4,5) ways to select 2nd digit = 5 (either of 1,2,3,4,5) ways to select 3rd digit = 5 (either of 1,2,3,4,5) total = 5*5*5 = 125

@bangalorian! Now that's better even a newbie can understand that's why I asked you to explain it because others can understand it easily. P.S: Actually! I did have idea after discussion with Hussain15 but wasn't sure and also wanted others views. _________________
