With n dots on each side the total number is n + (n-1) + (n-2) → 3n -3

Just plug in 358 for n.

P(A) + P(B) = P(A or B) + P(A and B)

P(A) + 0.5 = 0.59 + 0.26

You can take it from here!

Here are some intermediate steps:

As follows:

A number cube is tossed 24 times and lands on 1 three times and on 2 four times.

1. Find the experimental probability of landing on 1.

p_exp = 3/24 → 1/8

2. Find the theoretical probability of not landing on 1.

p_theory = 1 - 1/6 → 5/6

3. Find the theoretical probability of landing on 2.

p_theor = 1/6

4. Find the experimental probability of not landing on 2.

p_exp = (24 - 4)/24 → 5/6

5. State the difference between theoretical and experimental probabilities.

You can use the above to answer this.

As follows:

.

Volume of a pyramid = (1/3)*base area*height

Using Heron's formula for area of a triangle we have:

semi-perimeter:   s = (5 + 7 + 7.5)/2 = 9.75cm

base area = sqrt[s*(s-5)*(s-7)*(s-7.5)] ≈ 16.928 cm²

volume = 16.928*10 = 169.28 cm³

.

(9x^2y^3) (12x^-3y^5) (2xy) → (9*12*2)*(x^2*x^-3*x)*(y^3*y^5*y) → 216*(x^[2-3+1])*(y^[3+5+1]) → 216*x^0*y^9 → 216*y^9

.

I've assumed your question was how many people had logged on in up to a minute above. If you meant something else, there might still be enough information in the image to answer the question.
