Acertain 5-digit combination lock can be reset with a new combination. the lock uses numbers from 1 to 6. after a friend accidentally resets it to an unknown combination, what is the probability that you guess the combination that opens the lock? a. 100,000 b. 7,776 c. 1100,000 d. 17,776

1 / 7776

Step-by-step explanation:

The probability of guessing 1 number in any of the 5 positions is 1/6 .

So the probability of doing this 5 times = (1/6)^5   = 1 / 7776.

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
