1. A fair 20-sided dice with faces numbered from 1 to 20 is rolled. The event M is defined as “the number obtained is a multiple of 3”.
a. Determine P(M). If the dice is rolled 100 times.

b. How many times would you expect to get a multiple of 3?

you wouldn't get to many unless every time you roll you get an odd number and if you end up with that you can expect to get a number counted by 3 at least 6 times

0.84 dang lotta people are looking for this lol or if you round up its 1 but the overall answer to that is 0.84

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.

step-by-step explanation:
