2 and 1/2 sinc 3 over 3 is 1 and add that to 3/2 then simplify
The equation to find the right triangle is a^2+b^2=c^2 or the Pythagorean Theorem.
a^2+b^2=c^2 Substitute the values
18^2+26^2=c^2 Solve the powers
324+676=c^2 Simplify
1000=c^2 Solve the the square
31.6=c
Answer:
The probability is
Step-by-step explanation:
We are going to modeled this problem from the number of heads.
Let be H : ''The number of heads after five flips''
H can assume the following values :
h = 0
h = 1
h = 2
h = 3
h = 4
h = 5
H ~ Bi (n,p)
H ~ Bi (5,0.5)
H can be modeled as a Binomial random variable.
In which p = 0.5 is the success probability (the probability of head in one flip of a fair coin)
n = 5 is the number of times that we flip the coin.
We are also assuming independence in each flip.
The probability function for H is
For all the possible values of H
H ≥ 3 is the event that puts Polya on the 7th floor or higher.
Now we calculate the probability of H ≥ 3
Therefore, the probability of each of her next five stops is on the 7th floor or higher is
