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
B.)greater than five but less than six
Answer:
See the attachment
Step-by-step explanation:
A slope of -3/5 means the line drops 3 units for each 5 units it goes to the right. Then you can find another point on the line by going 5 uints to the left (to x=-2) and 3 units up (to y=1).
Plot the given point and the one just computed and draw the line through them.
Answer: x= -1, y= -3
Step-by-step explanation
solve like a system of equations
x-y-2 = 0
+
x+y+4=0
------------
2x+2=0, 2x= -2, x= -1, then plug that back into either equation
-1+y+4=0, y+3=0, y= -3
