Answer: The entire term b^2 − 4ac must be divided by 2a before its square root can be determined.
Answer:
(A) 0.08
Step-by-step explanation:
P(A) = 0.8
P(B) = 0.1
P(A and B)
= 0.8 x 0.1

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
The answer is 14.4
