Q1. 1. What is one to one function?
Ans. 
A one to one function is a function where each input has a unique output.
• Also known as an injective function.

• No two inputs can have the same output.

• For example, f(x) = x + 2 is a one to one function.

• However, f(x) = x^2 is not a one to one function as both x and -x have the same output.

Q2. 2. What is the domain and range?
Ans. 
Domain is the set of all possible input values and range is the set of all possible output values of a function.
• Domain can be represented as x-values in a function.

• Range can be represented as y-values in a function.

• Domain and range can be finite or infinite.

• For example, in the function f(x) = x^2, the domain is all real numbers and the range is all non-negative real numbers.

Q5. 5. What is conditional probability?
Ans. 
Conditional probability is the likelihood of an event occurring given that another event has already occurred.
• It is calculated by dividing the probability of the intersection of the two events by the probability of the given event.

• It is denoted by P(A|B), where A is the event we want to find the probability of and B is the event that has already occurred.

• Example: What is the probability of getting a head on the second ...read more
