If you flip a fair coin 4 times, what is the probability that you will get exactly 2 tails?

Most likely 50% that you will get exactly 2 tails

Step-by-step explanation:

Fair coin:  2 sides: heads and tails.  You flip it four times.  There is 50% you will get 2 heads and 50% you will get 2 tails.

- If 50% doesnt work you can always put 1/2.  I hope I helped :)

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.
