Hypothetical.) Suppose a certain person's reaction time, inseconds, for pressing a button on a visual cue has the followingcumulativedistribution function:

f(x)=1((1)/((x+1)3)) x > 0

What is the probability the person's reaction time will be between 0.9 and 1.1 seconds? (That is, 1 second, give or take a tenth of a second.)

Give the probability in decimal form, rounded to four decimal places.
