14. A combination lock uses three numbers between 1 and 91 with repetition, and they must be selected in the correct sequence. Which of the five counting rules is used to find that number? How many different"combinations" are possible? Is the name of "combination lock" appropriate? If not, what other name would be better? Which of the five counting rules is used to find that number? A. Permutations rule (when all of the items are different) B.Combinations rule C.Factorial rule...
The dial on a combination lock shows the integers 0 through 39. Turning the dial to three specific numbers (in order) opens the lock. a) How many different locks can a manufacturer produce before they have to reuse combinations, if numbers cannot be repeated in a combination (i.e., 25-17-25 is not allowed)? How many different locks can a manufacturer produce before they have to reuse the combination if numbers can be repeated in a combination?
4. (3 pts) A combination lock has a four-digit combination nin^ngn4, where ni,n2, ng, and n4 are integers in {0,1,...,9}. (a) (1 pt) How many lock combinations are possible if each digit can be repeated? (b) (2 pts) If the digits in the combination cannot be repeated, then what is the probability of someone guessing the correct four-digit combination? 3 4. (3 pts) A combination lock has a four-digit combination nin^ngn4, where ni,n2, ng, and n4 are integers in {0,1,...,9}....
To open a combination lock, you turn the dial to the right and stop at a number; then you turn it to the left and stop at a second number. Finally, you turn the dial back to the right and stop at a third number. If you used the correct sequence of numbers, the lock opens. If the dial of the lock contains 12 numbers, 0 through 11, determine the number of different combinations possible for the lock. Note: The...
A combination lock has 40 numbers written on it. If you guess the correct 3 numbers in order the lock will open. A. What is the probability of opening the lock if its poorly made and you can land on the correct number +/- 1 and have it still work? I.e 17 becomes {16,17,18} B. what is the probability of opening the lock if the combination is set to a birthday and (b) holds?
For each of the following combinations of quantum numbers, make changes that produce an allowed combination. Count 3 for cach change of n, 2 for each change of land 1 for cach change of me. Which quantum number needs to be changed to produce the lowest possible count that you can obtain? 2. n = 3,1 = 0, m = -3 1 m b. n = 5,1 5, m 4 On c. n = 3,1 = 3, m = -3...
A locker combination is made up of three numbers from 0 to 99. How many different locker combinations can there be?
How many combinations are there for a lock with four entries, where each entry can be 0-9, a-z, or A-Z?
Problem 05 If a number cannot be IMMEDIATELY repeated, how many different three number combinations are possible for a combination lock with numbers 0, 1,2....29
Declare a class ComboLock that works like the combination lock in a school or gym locker.. The lock is constructed with a combination dial numbers between 0 and 39. The constructor sets the three "secret" numbers and the current position to 0. The reset method resets the dial so that it points to 0. The turnLeft and turnRight methods turn the dial by a given number of ticks to the left or right. The open method attempts to open the...
