If there are that many things missing then go left to right; 5+1 then multiply the sum by ten
5+1=6
6x10=60
I hope I was helpful
I can’t tell without the question
The sibling cab either be male or female.
so, the required probability is 1/2
X=2W+1-1/Y
YOU SUBTRACT 2/Y TO START TO GET X ALONE.
WHICH WOULD MAKE IT 2X=4W+2-2/Y.
THEN YOU MUST DIVIDE BOTH SIDE BY TO FINISH GETTING X ALONE WHICH WOULD GIVE YOU YOUR ANSWER
