I think is
(x + y ) ( 2x - xy + 2y)
2x2 - x2y + 2yx + 2xy - xy2 + 2y2
Answer:
0.07072
Step-by-step explanation:
Red Blocks= 31
Green Blocks= 47
Yellow blocks = 23
Purple blocks= 24
Total= 31+47+23+24= 125
P(Yellow) = 23/125
P(Purple)=24/125
NOTE: AND (X), OR (+)
P(yellow yellow or purple purple)
= P(Y and Y) + P(P and P)
=(23/125 X 23/125) + (24/125 X 24/125)
=529/15625 + 576/15625
=1105/15625
=221/3125
=0.07072
Therefore:
Probability of Picking Yellow Yellow or Purple Purple is 0.07072.
