Let's manipulate the expression a little bit and see what we come up with: we have
We can simplify the fraction as
Since both 
and 
are positive, their sum will be positive as well. In other words, we can rewrite the fraction as
So, the sign of this fraction depends on the sign of 
. If its positive, then the whole fraction is positive (product of 4 positive factors). If it's negative, then the whole fraction is negative (product of 3 positive factors and a negative one).
In other words, we arrived to the desired conclusion:
To determine the probability, the formula is by number of successful outcomes divided by number of possible outcomes. The number of possible outcomes in this problem is 4.
So to compute the probability distribution:
The number of times that 0 G appeared is 0.25 which is represented by BB which is 1/4.
The number of times that 1 G appeared is .5 which is represented by BG and GB which is 2/4.
The number of times that 2 G appeared is .25 which is represented by GG which is 1/4.
The probability distribution will look like this:
X Px(x)
0 .25
1 .5
2 .25
Answer:
Step-by-step explanation:
C.
The multiplicative property states that by multiplying both sides of an equation gives you the same sum on both sides. By multiplying both sides by -2, the equations are the same by the property.
