Let us assume that we are allowed to print so called college money used for shopping only within campus. the money is composed a unique serial numbers like m20130bc. it always starts with m, follows with five digital numbers chosen from 0 to 9, and then two letters chosen from a to z. a. what is the total number of such series numbers? b. what is the probability of getting the serial number mmm? c. what is the probability of getting a serial number whose last two letters to be aa?

a. 67600000

b. 0.0001396

c. 0.001479

Step-by-step explanation:

a. Since it is a permutation with repetition the formula is:

Where is the number of optionss, here you will use and , one for the numbers and the other for the letters. The exponent corresponds to how many times you have to choose a number (5 times) or a letter (two times because the first letter is always the same), then:

b. The probability of getting that exactly serial number is 1 divided by the total of possibilities:

C. The probability is the number of serials ending with AA divided by the total. The serial ending with AA can have any numbers then   and

welll its a very hard question but ill

step-by-step explanation:

first you take the 6 dollars and add 10 to it then add the 50 to that then multiply by 8 with xy and your answer will be

hope this

a

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
