If you have two P(A) or two P(B) then the probability would not be 50% <em>{0.5}</em> it would be 100% <em>{0.10}</em> because it would be the same.
Step-by-step explanation:
The probability that Events A and B both occur is the probability of the intersection of A and B. The probability of the intersection of Events A and B is denoted by P(A ∩ B). If Events A and B are mutually exclusive, P(A ∩ B).

If you buy a matching red shirt and and a matching set of red pants it wouldn't be 50% of the outfit unless you wore the shirt with blue pants or wore the pants with a blue shirt.
I'm solving your system by substitution. 2x-4=5, 5x+4y =2 Step# 1: solve for x 2x - 4+ 4= 5 + 4( add +4 to both sides) 2x = 9 x = 9/2 Step# 2: solve for y
if 3/4 where made by family and 1/4 where made my friends then there isnt anymore to be made that is 4/4 lol so i guess that you made none i do not know i am trying to help but its a little confusing hope i helped though
