Answer:
2/15
Step-by-step explanation:
Step one:
given data
sample space
1 elephant,
4 bears,
3 cats, and
2 dogs.
sample size= 1+4+3+2= 10
Required:
By selecting without replacement, the probability that she chooses a bear both times
Step two:
the first event= Pr(bear)= 4/10= 2/5
the second event, the sample size is now 9 and the number of bears is now 3
Pr(bear)= 3/9= 1/3
Hence, the probability that she chooses a bear both times
= 2/5*1/3
=2/15
1/10(0.2)
=(1/10)(0.2/1)
=(1)(36028) / (10)(18014)
=0.02
5/9
5 times 4= 20
12 times 3=36
20/36=5/9
Answer is A) -1 because it they are parallel then they have the same slope. If the green line has a -1 slope so does the red line
