Two things make up a vector: magnitude and direction.

Two vectors having the same magnitude doesn't guarantee that they have the same direction, and therefore it's not a guarantee that they are equal.

. In a high school graduating class of 100 students, 47 studied mathematics, 61 studied physics, and 25 studied both mathematics
gtnhenbr [62]

Answer:

given,

Probability of student studying math P(M)=\dfrac{45}{100} = 0.45

Probability of student studying physicsP(P) = \dfrac{61}{100} = 0.61

Probability of student studying both math and physics together P(M∩P) = \dfrac{25}{100} = 0.25

a) student took mathematics or physics

P(M∪P) = P(M) + P(P) - P(M∩P)

             = 0.45 + 0.61  - 0.25

             = 0.81

b) student did not take either of the subject

P((M∪P)') = 1 - 0.81

               = 0.19

c) Student take physics but not mathematics

P(P∩M') = P(P) - P(P∩M)

             = 0.61 - 0.25

             = 0.36

studying physics and mathematics is  not mutually exclusive because we can study both the subjects.
