Answer:
60%
Step-by-step explanation:
The table with proper formatting is attached below.
We have to find the probability that a randomly selected person is 41-55 in age or prefers drinking Dr. Fizz.
Total number of people = 100
People in range 41 - 55 = 30
People who prefer Dr. Fizz = 30
People in range of 41 - 55 and prefer Dr. Fizz = 0
The general formula of probability in case of OR of two events is:
P ( A or B ) = P(A) + P(B) - P( A and B)
So for the given case we can write:
P (Person is in 41-55 range OR prefer Dr. Fizz) = P (Person is in 41 - 55 range) + P(Prefers Dr. Fizz) - P(Is in 41-55 range And prefers Dr. Fizz)
P (Person is in 41-55 range OR prefer Dr. Fizz) = 30/100 + 30/100 - 0/100
= 60/100
= 60%
Thus there is a 60% probability that a randomly selected person is 41-55 in age or prefers drinking Dr. Fizz
Answer:
In Δ CFD , CD is the LONGEST side.
Step-by-step explanation:
Here, the given Δ CSD is a RIGHT ANGLED TRIANGLE.
Now, as we know in a right triangle, HYPOTENUSE IS THE LONGEST SIDE.
So, in Δ CSD SD is the longest side as SD = Hypotenuse.
Now, an altitude CF is drawn to hypotenuse SD.
⇒ CF ⊥ SD
⇒ Δ CFD is a RIGHT ANGLED TRIANGLE with ∠ F = 90°
and CD as a hypotenuse.
⇒ In Δ CFD , CD is the LONGEST side.
Hence, CD is the longest side in the given triangle CFD.
