Answer:
31.77% probability the surgery is successful for exactly five patients.
Step-by-step explanation:
For each patient, there are only two possible outcomes. Either the surgery is successful, or it is not. The probability of the surgery being successful for a patient is independent of other patients. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

In which
is the number of different combinations of x objects from a set of n elements, given by the following formula.

And p is the probability of X happening.
A surgical technique is performed on seven patients.
This means that 
You are told there is a 70% chance of success.
This means that 
Find the probability the surgery is successful for exactly five patients.
This is P(X = 5).


31.77% probability the surgery is successful for exactly five patients.
The car went about 35.34 miles per gallon.(How? Divide 7.3 into 257 and you got your answer.)
<span>17x-2=7x+8
We simplify the equation to the form, which is simple to understand
<span>17x-2=7x+8
We move all terms containing x to the left and all other terms to the right.
<span>+17x-7x=+8+2
We simplify left and right side of the equation.
<span>+10x=+10
We divide both sides of the equation by 10 to get x.
