The answer to your question is 5.100
It is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.
As given in the question,
Number of cards are unknown.
Number of red cards are unknown in the starting of experiment.
Number of times process done =10
For binomial random variable number of red cards should be known.
Therefore, it is not binomial random variable , since the number of red cards is unknown in the deck of cards in the starting of experiment.

Answer: Matrix B is non- invertible.
Step-by-step explanation:
A matrix is said to be be singular is its determinant is zero,
We know that if a matrix is singular then it is not invertible. (1)
Or if a matrix is invertible then it should be non-singular matrix. (2)
Given : A and B are n x n matrices from which A is invertible.
Then A must be non-singular matrix. ( from 2 )
If AB is singular.
Then either A is singular or B is singular but A is a non-singular matrix.
Then , matrix B should be a singular matrix. ( from 2 )
So Matrix B is non- invertible. ( from 1 )
