Step-by-step explanation:
From the question we are told that
The number of times is n = 20
The probability of getting three or more heads in a row is 
The probability of getting three or more heads in a row or three or more tails in a row is 
Generally given that it is a fair coin , then 
Here P(T) is probability of getting three or more tails in a row
Generally the probability of getting three or more heads in a row and three or more tails in a row is mathematically represented as
=>

In order for them to raise the same amount of money, they will need to sell 12 bags of cookies.
<h3>What is the equation?</h3>
A mathematical statement consisting of an equal symbol between two algebraic expressions with the same value is known as an equation.
If x is no of bags of cookies must they sell in order for them to raise the same amount of money;
For sister 1 ;
You start out with $24 and sell each bag of cookies, c, for $3.The amount of money the person raised;
y = $ 24 + ($3 / bag)x
y=24+ 3x
For case 2;
y= $ 0+ ($5 / bag)x
y=5x
If both raise the same amount of money(y) then;
24 + 3x = 5x
5x-3x=24
2x=24
x=12
Hence, the number of bags of cookies will be 12 must they sell in order for them to raise the same amount of money.
