Some memory based questions:
- Yourself
- Why Data Science?
- If you have n numbers how many bits are required to present that numbers?
- If you have a matrix of $3\times 3$ which is not invertible then what you will say about the Rank of that matrix.
- How many probability distribution function are there which you know?
- Explain Binomial distribution? Mean and variance?
- In which distribution Mean and variance are same?
- You have given a number; you have to find the number of digits which are divisible by $3.$ Eg. If number is $123$ then it should return $1$ as output as only $3$ is divisible by $3.$
- What is the complexity to find a number from BST.
- You have a bidirectional graph max number of edges in that graph?
- You have $2$ events $A$ and $B. P(A)=0.6, P(B)=0.7$ what you can say about it disjoint event or dependent? Axioms of probability.
- There is a person $A,$ who has $2$ kids. If the first child is girl then what is the probability that $2^{\text{nd}}$ child is also girl.
