Answer:
the correct option is d. 0.02
Step-by-step explanation:
We have the following events:
x: A drought occurd
y: Water rationing.
Therefore, according to the plaster we have:
P [x] = 0.20
P [y | x] = 0.10
Now P [it is a drought and water rationing happens] =
P [x n y] = P [y | x] * P [x] = 0.10 * 0.20 = 0.02
Which means that the correct option is d. 0.02
Yes the first choice is the right choice.
Remember that the 3rd root range is from -infinity to infinity.
No, if you are subtracting a bigger than the one it is being taken from then the answer will be negative. Ex:5-10=-5

Answer:
9
Step-by-step explanation:
Given: Subtract 9 from 10. Multiply this difference by 3, square this product.
Now, lets simplify it.
![[(10-9)\times 3]^{2}](https://tex.z-dn.net/?f=%5B%2810-9%29%5Ctimes%203%5D%5E%7B2%7D)
Using PEDMAS rule to solve it
First working on Parenthesis
= ![[(1)\times 3]^{2}](https://tex.z-dn.net/?f=%5B%281%29%5Ctimes%203%5D%5E%7B2%7D)
Opening the parenthesis
= ![[1\times 3]^{2}](https://tex.z-dn.net/?f=%5B1%5Ctimes%203%5D%5E%7B2%7D)
= ![[3]^{2}](https://tex.z-dn.net/?f=%5B3%5D%5E%7B2%7D)
= 
∴ Answer is 9.
