Answer:
The chance of getting exactly 3 hits is = 0.20
Step-by-step explanation:
P.S - The exact question is -
As given,
F(x) = 0 , x < 1
0.30 , 1 ≤ x < 2
0.56 , 2 ≤ x < 3
0.76 , 3 ≤ x < 4
0.9 , 4 ≤ x < 5
1 , 5 ≤ x
Now,
f(x) = 0.30 , x = 1
0.56 - 0.30 = 0.26 , x = 2
0.76 - 0.56 = 0.20 , x=3
0.9 - 0.76 = 0.14 , x = 4
1 - 0.9 = 0.1 , x = 5
0, otherwise
Now,
The chance of getting exactly 3 hits is = f(x = 3) = 0.20
The given vectors are and
Two vectors are said to be orthogonal if they are perpendicular to each other. i.e. the dot product of the two vectors is zero.
Let us consider the dot product of the vectors
which is not equal to zero. Hence, the given vectors are not orthogonal.
Two vectors are said to be parallel if one vector is a scalar multiple of the other vector.
Here we can observe that the from the given vectors, one vector can not be expressed as the scalar multiple of the other vector.
Hence, the given vectors are neither parallel nor orthogonal.
