The possible combinations are:
1,9
2,8
3,7
4,6
9,1
8,2
7,3
6,4
Total straws: 9
Probability of first being 1: 1/9
Probability of second being 9: 1/8
Probability of both: 1/9 x 1/8 = 1/72
This will be multiplied by 8 as there are 8 possible combinations:
8 x 1/72
= 8/72
= 1/9
1
Factor out the common term 3
3(y^2-3x)=0
2 Divide both sides by 3
y^2-3x=0
3 Add 3x to both sides
y^2=3x
4 Take the square root of both sides
y= positive or negative √3x
