Acontinuous random variable may assume:
-any value in an interval or collection of intervals
-only integer values in an interval or collection of intervals
-only fractional values in an interval or collection of intervals
-only the positive integer values in an interval

-any value in an interval or collection of intervals

Step-by-step explanation:

Discrete random variables are only integers in the interval.

Continuous random variables are all the values(integers, fractional, negative, positive) in an interval, or a collection of intervals.

The correct answer is:

-any value in an interval or collection of intervals

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
