Question

James has a 5 digit passcode on his computer. The first three digits are numbers from 0 to 9 and the last two digits are letters from the alphabet. If the numbers and letters can repeat, what is the probability that the passcode is 417GR? Select one: 1/676000 5/676000 3/16900 1/338000

Answer 1

5/676000 because 4, 1, and 7 are in between 0-9, and G and R are in the alphabet

Answer 2

Explanation:

Givens

The code is 5 "digits" long

The code has 3 numbers in front. These numbers can be anything from 0 to 9 which is 10 digits. Repeats are allowed.

The code has 2 letters (26 in the English Alphabet) which can also repeat.

Solution.

Numbers: 10 * 10 * 10 = 1000

Letters: 26 * 26 = 676

Combined: 676000

So the answer is 1/676000
