You could make a tree diagram
H T ← 1st toss
H T H T ← 2nd toss
H T H T H T H T ← 3rd toss
etc ,,, then count the combination of favorable outcomes
Using a calculator:
Total number of outcomes is
= 128
Probability of getting exactly 3 heads is found using the follow calculator feature: binompdf(7, 0.5, 3)
ANSWER: Typed into the calculator as follows binompdf(7,0.5,3)×128 = 35

Answer:
Step-by-step explanation:
Lets rename the variables as
P = peppermint
S = squirrel.
Now, let's see how many different ice cream orders can we made with this two flavours.
We got 3 scoops. So we can place on the first scoop P.
And on top, we can add P P, S S, S P , or P, S.
So the Triple Decker would be ( PPP, PSS, PSP , PPS)
So we can get 4 kind of flavours with Peppermint on the first scoop.
And if we use a scoop of Squirrel on the first level. We would also have
( SPP, SSS, SSP, SPS)
So we can order 8 different ice cream orders. This is called a variation with repetition. And the math function that represents it is:
Where 2 is different variables that we can use (Pepper or Squirrel), and 3 is the number of places where we can place the variable.(the order of the scoop)
