Answer:
Being a student and preferring “shark” are not independent events
Step-by-step explanation:
Let A be the event that the selected person is a student and B the event that person prefers sharks.
Total number of students =100
Hence P(A) =
P(B) = Persons who prefers sharks /total persons
=
P(AB) = no of persons who are students and who prefer sharks/total persons
=
P(A)P(B) =
Since P(AB) does not equal P(A) P(B), we find that
A and B are not independent.
Being a student and preferring “shark” are not independent events
Answer:
D = 12.94 m
Step-by-step explanation:
Coordinates of first tree = A(0,8)
Coordinates of second tree = A(12,4)
We need to find the distance between the two trees. We can find it using distance formula for coordinates as follows :
We have, x₁ = 0, x₂ = 12, y₁ = 8, y₂ = 4
Now using distance formula,
So, the distance between the two trees is 12.64 m.
