7x/x-4 * x/x+7
mutiply the numerators together
(7x)(x)= 7x^ 2
mutiply the denominators together
(x-4)(x+7)
(x)(x)(7)(x)= x^2+7x
(-4)(x)(-4)(7)= -4x-28
x^2+7x-4x-28
x^2+3x-28
Answer:
7x^2/x^ 2+3x-28
The sum of the two is three over ten or 3/10
If we will roll a fair die then the outcomes wil be 1,2,3,4,5,6.
Hence, the total number of events= 6
3,4,5 and 6 are greater than 2.
So, there's 4 events which are greater than 2.
Now the formula to find the probability is:
probability=
=
=
So, the probability of getting greater than a 2 is 2/3.
