Answer: 0.05
Step-by-step explanation:
Given : Interval for uniform distribution : [46.0 minutes, 56.0 minutes]
The probability density function will be :-

The probability that a given class period runs between 50.75 and 51.25 minutes is given by :-

Hence, the probability that a given class period runs between 50.75 and 51.25 minutes = 0.05
Answer:
So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with
3/1 times x = 2193
3/1 just equals three, so you write it down as 3.
3x = 2193
To isolate 3x, you need to divide by 3.
x = 731
Hope this helped :)
