If a point within the density curve is chosen at random, what is the probability that the value lies between 2.25 and 4.75?
0.025
0.375
0.417
0.639
0.75

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .

6mm^3 or .6cm^3

factor trees are nice.
