This is an example hope this helps
There are 8 black chips and 6 white chips, 14 chips in total. In this situation the probability to pick a black chip is 8/14=4/7.
When one white chip was removed, then only 5 white chips left and the total number of chips became 13. In this situation the probability to pick a black chip is 8/14=4/7.
When second white chip was removed, then ther left 4 white chips and the total number of chips became 12. Now the probability to pick a black chip is 8/12=2/3 as needed.
Answer: Must be removed 2 white chips. Correct choice is B.
In the given equation the value of the x be a x = U*ky-y.
According to the statement
we have to find that the value of the x from the given statement.
So, For this purpose, we know that the
An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
From the given information:
The given statement is
U=x+y/ky
now, rearrange the terms then
U*ky=x+y
U*ky-y = x
And then the value f the x become
x = U*ky-y.
So, In the given equation the value of the x be a x = U*ky-y.
