Answer:
1 - 1/10
Step-by-step explanation:
As strange as it may seem, the easiest way to answer this question is to calculate the probability of selecting an elephant first and then to subtract this probability from 1:
Adding up the Numbers of animals, we get 12+4+3+11, or 30. The probability of selecting an elephant is thus 3/30, or 1/10.
Thus, the probability of NOT selecting an elephant is 1 - 1/10 (Answer A).

me dont know man why yall givin me this question
Step-by-step explanation:
ahhhhhhhhhhhhhhhhh
Answer:
Ta có: P (
A
) P (
B
) = 0
,
12
. Vì P (
A
B
) = 0
,
2 ≠ 0
,
12 = P (
A
) P (
B
)
nên hai biến cố A và B không độc lập với nhau.
Step-by-step explanation:
The answer is A. I just finished the test.
Company C services 16 office suites.
Company A services 1/3 of the suites and Company B services 2/5; together they service 1/3+2/5. Find a common denominator; 15 is the smallest:
1/3=5/15
2/5=6/15
5/15+6/15 = 11/15
This means that 1-11/15 = 4/15 of the suites are serviced by Company C.
4/15 of 60 = 4/15(60) = 4/15(60/1) = 240/15 = 16
