Step-by-step explanation:
dont trust me i dont know the answer sry
Given:
Length of first vector = 2 meters
Length of second vector = 4 meters
To find:
The vector which has a greater magnitude.
Solution:
We know that, magnitude of a vector represents the length of it.
The first vector that is 2 meters long has a magnitude 2.
The second vector that is 4 meters long has a magnitude 4.
Clearly, 4 is greater that 2, i.e., 4 > 2. So, magnitude of second vector is greater.
Therefore, the vector that is 4 meters long has greater magnitude.
nCr(20, 2) = 190 ways of selecting 2 from 20
nCr(10, 1) = 10 ways of selecting 1 from 10
To find the over all probability of winning,
Calculate the Harmonic Mean (19) and divide by 2
Equivalent to
1/ (1//190 + 1/10) =9.5
So the probability is 1/9.5 = 2/19.
