john has 300 yellow beads, 200 yellow beads, 700 green beads, 200 black beads and 100 grey beads. what is the probability of picking out a yellow bead? (simplify the answer) write like this = (a/b)

• 200/15

• 200/1500

• 20/150

• 2/15

what is/are included in factorization of algebraic expressions? (multiple selection is allowed)

• coefficient

• variable

• operation

• subject

factorize this=

16m+4m²n

solve the following=

30a + 72c - 12b + 270b - 23a + 2c (use alphabetical order)

set A = {stars in the universe}

• infinite set

• subset

• finite set

• super set

 $\ \ \ \ \left(A\ \cap\ B\right)\subset C\$  A= {20,35,27)               B= {20,40,35,27,50,46,23)
           C= {30,23,35,40,73,20,57,27}               (first find bracket then see if the answer is a subset of C) 

• I don't know

• true

• too Hard!!!

• false
