A combination lock will open when the right choice of three numbers (from 1 to 36) is selected. How many different lock combinations are possible?
36x35x34
It doesn't say all three have to be different... this isn't "without replacement"
36x36x36 is this multiple choice?
ya. then 36^3
That should be correct... 36 * 36 * 36 = 36^3 36 choices for the first #, and for each of those, 36 choices for the 2nd #, and for each of those, 36 choices for the last number
A. 39,304 B. 117,912 C. 34 D. 102 here are my options if it were (1 to 34)
Is it 34 or 36? 34^3 is option A
okay thank you so much!
option A!
I'm confused about where the 34 came from though... the problem said numbers 1-36
the original problem is the type of problem except i had different numbers (from 1 to 34)
sorry for the confusion
oh :) Ok, got it. Yes, it's just the number of choices for each number all multiplied together. So if you had a combo lock with 10 numbers, you would have 10 * 10 * 10 possible combinations. etc.
