Given P(A)=0.3P(A)=0.3, P(B)=0.63P(B)=0.63 and P(B|A)=0.79P(B∣A)=0.79, find the value of P(A\text{ and }B)P(A and B), rounding to the nearest thousandth, if necessary.

a) justify

step-by-step explanation:

justifying is just part of everyday life. justify kind of means proof so i think the answer is a) justify.

step-by-step explanation:

1

step-by-step explanation:

it's the only multiple of both and the least

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
