7 = r^1/2 is the same as saying 7 = square root of r. So, to get rid of the square root sign on the r, you need to square it, and when you do something to one side of the equation, you have to do the same to the other side. So after squaring both sides, you get 49 = r.

Step-by-step explanation:
Given:
The numbers are .
To find:
All the values that cannot be probabilities.
Solution:
We know that,
The minimum value of favorable outcomes is 0 and the maximum value is equal to the total outcomes. So, the value of probability lies between 0 and 1, inclusive. It other words, the probability lies in the interval [0,1].
From the given values only lie in the interval [0,1]. So, these values can be probabilities.
The values does not lie in the interval [0,1]. So, these values cannot be probabilities.
Therefore, the correct values are .
So, We Need To Multiply.
