Since the combination can contain number (0-9) and letter (A-Z), therefore the total characters to choose from is:

10 + 26 = 36

Since there are 8 characters, therefore the total number of combinations is:

Combination = 36^8 = 2.821 x 10^12

 

The probability that the two will have similar passwords will be:

Probability = (1/2.821 x 10^12) ^2

Probability = 1.26 x 10^-25

 

The probability is very low.

Can somebody explain a unit rate to me? I am struggling in math.
Phoenix [80]

Unit rates actually are utilized by people frequently in every day life. A standard work week undertaken by a typical person is 40 hours per week. Unit prices are useful at grocery stores. For example, if five potatoes cost $5, the unit price is determined by dividing the total price by the number of individual potatoes, or $5 divided by 5.
