The probability would be split for this problem cause knowing with 20 coins , you can split that even amount ... here's what I would do..
Michelle has 20 coins , but only half of them land on heads and others on tails
As for a half , halves are always equaling to 1/2 or 50 (%) knowing we have 20 , you can evenly split that number of coins in a equal position
So ask your self .. what is half of 20? hmmm .. oh I got it , its 10! so knowing you have 20 but then later you split into half which is 10 ... meaning and knowing you have a 50% probability of getting the 20 coins hitting onto tails
hope this helps!

Answer:
See below.
Step-by-step explanation:
So we know that a gym membership costs $25 plus $14 each month.
In other words, the one-time cost is $25 and there will be a cost of $14 each month.
We can write this as:

Where f(x) equals the total cost given the number of months x.
For 6 months, the total cost will be:

Let width = w then we have the equation:-
w(w + 12) = 448
w^2 + 12w - 448 = 0
(w - 16)(w + 28) = 0
w = 16
Answer: the dimensions of the window are width 16 by height 28 inches
