A) probability of she not drawing a yellow beads or green beads is probability of she drawing red or white. Red+ white = 30. There are total of 100 beads. That means that asked probability is:
30/100
b) its oposite that result from a) yellow beads + green beads = 70
probability is: 70/100
X + (-y) = -2.3 + ( - (-5.9) ) = -2.3 + 5.9 = 3.6
You would take 3/4x=36
Then you would divide each side by 3/4 and 36÷0.75=48
There are 48 people in the club. Hope this helps!
You do 73 -7=66 then do 66÷11=6 with make x=6
