Answer:
a) 1/2
b) 6/100
c)1/4
I'll explain how I got these answers later.
Step-by-step explanation:
Total highlighters = 10
A : favourable cases / total cases = 5/10 = 1/2
B : favourable cases/ total cases * favourable cases/ new total cases
2/10 * 3/9 = 1/5 * 1/3 = 1/15
C : favourable cases/ total cases * favourable cases/ new total cases
5/10 * 4/9 = 1/2 * 4/9 = 4/18
y=0
6y+2=-2(2y-1)
Distribute
6y+2 = -4y +2
Add 4y to each side
6y+2 = -4y +2+4y
6y +2 =2
Subtract 2 from each side
6y +2-2 = 2-2
6y = 0
