8. A surgical technique is performed on seven patients. You are told there is a 60% chance of success. Find the probability that the surgery is successful for (a) exactly five patients, (b) at least five patients, and (c) at most two patients.
Percentage
A percentage is a number indicated as a fraction of 100. It is a dimensionless number often expressed using the symbol %.
Algebraic Expressions
In mathematics, an algebraic expression consists of constant(s), variable(s), and mathematical operators. It is made up of terms.
Numbers
Numbers are some measures used for counting. They can be compared one with another to know its position in the number line and determine which one is greater or lesser than the other.
Subtraction
Before we begin to understand the subtraction of algebraic expressions, we need to list out a few things that form the basis of algebra.
Addition
Before we begin to understand the addition of algebraic expressions, we need to list out a few things that form the basis of algebra.

10. Of students ages 16 to 18 with A or B averages who plan to attend college after
graduation, 78% cheated to get higher grades (Source: "Who's Who Among American
High Schools Students"). Ten randomly chosen students with A or B averages that plan
to attend college after graduation were asked, “Did you cheat to get higher grades?"
