7 0

Answer:

Step-by-step explanation:

It doesn't matter what order they are chosen in, so the numerator is 64C3.

The total number of ways that you can choose any 3 crayons is 64 * 63 * 62

P(r and y and b) = 64! / (62! 3!) // 64 * 63 * 62

P(r and y and b) = 64 * 63 * 62 / 6 // 64 * 63 * 62 = 41664 / 249984 = 0.167

What is the volume of this triangular prism? A triangular prism. The triangular base has a base of 28 centimeters and height of
mamaluj [8]

Answer:

The volume of the triangular prism is 5676.16 cm³

Step-by-step explanation:

The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.

Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'

V = Ah' where h = height of prism = 18.1 cm

So, V = bhh'/2

Substituting the values of the variables into the equation for V, we have

V = bhh'/2

V = 28 cm × 22.4 cm × 18.1 cm/2

V = 14 cm × 22.4 cm × 18.1 cm

V = 5676.16 cm³

So, the volume of the triangular prism is 5676.16 cm³
