In a sofa store 30% of the sofas are leather. 40% of the leather sofas are black. what percentage of the total number of sofas are made form black leather?

12%

Step-by-step explanation:

Given,

% of leather sofas = p(A) = 30% = 30/100 = 0.3

% of leather sofas that are black = p(B) = 40% = 40/100 = 0.4

The percentage of total sofas made from leather = p(A) * p(B)

= 0.3 * 0.4

= .12

= 12%
