Aston university creates a 10 digit student number as the university enrolls each student. the first two characters must be a digit 1 through 9. the next seven characters can be anything and the last digit just can’t be the same as the ninth character (i. e. the previous digit). how many student numbers are possible?

step-by-step explanation: the answer for wha if rt is 10 centimeters long, and wha is st? it’s 6

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
