A Dubai based gangster Chhota Vakil is in Switzerland. He wants to rob a bank there, whose locker code according to his information is an odd number between 50 and 450. He also knows that the numbers are from the set: 0, 1, 2, 3, 4, 5}. How many maximum trials he has to take to unlock the locker?

A numerical lock can be opened using any possible combination of these five digits 0, 1, 0, 3 and 2 (example 20031). John used all possible incorrect combinations on the 5-digit lock before finally opening the lock at the next attempt. How many total attempts did he make? The digits available are 0-5 in lock ​

5. There are three keys for three suitcases with different locks. Each key only fits one of them. What is the minimum number of trials needed to find a key for each?23456789

The diagram shows a security lock.You have to enter the correct code to open the lock. The correct code is B3Dan does not know the code.He enters at random one of the letters.He then enters at random one of the numbers.Work out the probability that Dan enters the correct code.

One day a thief plans to rob PQR bank. All the money in the bank is kept in a secret room. The secret room has N vaults arranged in a circle and the amount of money inside each vault will be displayed on the vault door. An alarm sounds If the thief attempt to break more than 2 of any 5 adjacent vaults and thief will be caught. Calculate the maximum amount of money that he can rob without sounding the alarm. Note: The vaults are arranged in a circle, the last vault is adjacent to the first one. Input Format: The first line contains an integer N which is the number of vaults. The next line has a sequence of positive integers of length N, giving the amount of cash in the vaults in order. Output Format: The maximum amount of money that the thief can rob without sounding the alarm. Constraints: N<=25, Amount in each vault <=50000 Sample Input 1: 9 1000 2000 1000 5000 9000 5000 3000 4000 1000 Sample Output 1: 15000 Explanation: The vaults 1, 5, 6 are looted, giving a total loot of (1000+5000+9000) = 15000 Sample Input 2: 10 1000 2000 3000 5000 9000 7000 6000 4000 7000 5000 Sample Output 2: 26000 Explanation: One way of getting the maximum amount is to loot vaults 4, 5, 9 and 10 giving a total of 26000. Hence the output is 26000. Note that no 5 adjacent vaults have more than 2 looted. give the code in c++

A person must enter a 4 digit code to gain access to his cell phone. He will enter codes until he is successful, however he cannot try more than 3 times or the phone will lock him out. Let S denote a successful attempt and F denote a failed attempt. What is the sample space for this random experime
