2) 12x- 28
3) 6 (3x+2)
4) 7x+2
Step-by-step explanation:
1) 5x +3 +4y-7+6x-y-3x
8x+3+4y-7-y
2) 4x3x-4x7
12x-4 x 7
3) 18x+12
6(3x+2)
4) 9x+ 1-7x +4+5x- 3
7x+1+4-3
Im sorry I wanted to answer it as quick as possible sorry if you dont understand.
Consider this option (2 ways for this):
1. Probability=1-[probability_all_boys].
for [probability_all_boys]=1/[all_possible_combinations];
for [all_combinations]=2³=8. It means that
Probability=1-(1/8)=7/8=0.875.
2. Probability=[needed_cases]\[all_possible_cases];
all possible combinations are:
bbb;ggg;bgg;bgb;bbg;gbg;gbb;ggb; - (where 'g' - girl, 'b' - boy) total 8.
needed cases: ggg;bgg;bgb;bbg;gbg;gbb;ggb, - total 7.
Probability=7/8=0.875
