<h3>Answer:</h3>
The cube of twice a number is 
.
Answer:
x+2/2(2x+1)
Step-by-step explanation:
Tamlin has x male action figures and x + 2 female action figures, so a total of x + x + 2, or 2x + 2 action figures. The probability of picking two female action figures without replacement is equal to the product of the probability of
-picking 1 female action figure from the total number and
-picking 1 female action figure after 1 has been removed.
The probability of picking 1 female action figure from the total is equal to the total number of female action figures divided by the total number of action figures.
The probability of picking 1 female action figure after 1 has been removed is equal to the total number of female action figures minus 1 divided by the total number of action figures minus 1.
Multiply these two expressions and simplify.
