P(A)=0.40
P(B)= 0.60
P(A and B)= 0.15
What is P( A│ B)?

0.25

Step-by-step explanation:

P(A/B) = P(A^B)/P(B)

= 0.15/0.60 = 0.25

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
