Explanation

A non-reversible square matrix (m = n)  is called singular or degenerate.

A square matrix is ​​singular only if the determinant is 0.

Explanation

The range of probability for each event lies between 0 and 1.

This means that the probability of any event can be a value from 0 (impossible event) to 1 (certain event).

Explanation

Total ways to draw 3 balls = C(15, 3) = 455

Ways to draw 3 red balls = C(5, 3) = 10

Probability = 10/455 = 2/91

Explanation

6P4 = 6 × 5 × 4 × 3 = 360.

The trade-off theory of capital structure tells us that:

Managers should seek an optimal mix of equity and debt that minimizes the firm's weighted average cost of capital,

which in turn maximizes company value

Explanation

Aₙ = a + n × d, where d = common difference  

Here, A₁ = a + d, A₂ = a + 2d, ..., b = a + (n+1)d

So,  

Aₙ = a + n × [(b − a)/(n + 1)]

Explanation

 We are given:

• Red balls = 8

• Blue balls = 7

• Green balls = 6

Total balls = 8 + 7 + 6 = 21

We are asked to find the probability that the ball is neither red nor green.

That means we want the probability that the ball is blue.

Number of favorable outcomes = Number of blue balls = 7

Probability = (Favorable outcomes) / (Total outcomes)

= 7/31

=1/3
$$721=13frac{7}{21} = frac{1}{3}
