Answer:
The probability that on any given day the water supply is inadequate 
Step-by-step explanation:
Given
α = 2 and β = 3
As per Gamma distribution Function

Expanding the function and putting the given values, we get -

8x^4y^213. I personally cannot figure out the numerator and denominator, sorry :)
Permutations
slot method
8 slots
1st slot has 8 choices
2nd has 7 because 1 went to first slot
3rd has 6
4th has 5
5th has 4
6th has 3
7th has 2
8th has 1
8*7*6*5*4*3*2*1=40320 ways
1 Expand.
8x-6-8=4+2x8x−6−8=4+2x
2 Simplify 8x-6-88x−6−8 to 8x-148x−14.
8x-14=4+2x8x−14=4+2x
3 Add 1414 to both sides.
8x=4+2x+148x=4+2x+14
4 Simplify 4+2x+144+2x+14 to 2x+182x+18.
8x=2x+188x=2x+18
5 Subtract 2x2x from both sides.
8x-2x=188x−2x=18
6 Simplify 8x-2x8x−2x to 6x6x.
6x=186x=18
7 Divide both sides by 66.
x=\frac{18}{6}x=

18
8 Simplify \frac{18}{6}

18
to 33.
x=3x=3
Done Hope this helps let me know if u have any questions thank you
