Suppose you choose a marble from a bag containing 2 red marbles, 5 white marbles and 3 blue marbles. you return the first marble to the bag and choose again. find p (red then blue)

Step-by-step explanation:

Given: Number of red marbles = 2

Number of white marbles = 5

Number of blue marbles  = 3

Total marbles =2+5+3=10

If we choose first marble from the bag, then the probability of having red marbles will be :-

If we choose second marble after replacement (total remains same) from the bag, then the prob ability of having blue marbles will be :-

Since, both the events are independent.

Therefore, the probability of choosing red marble then blue marble is given by :-

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
