Answer:

C. obtaining an even number when rolling a die

Step-by-step explanation:

Two events are independent when neither depends on the other. That is, the probability that one occurs is not affected by the occurrence, or lack of occurrence, of the other event. Their joint probability is the product of their individual probabilities.

__

Among the answer choices, all describe two independent events except C. Choice C describes one (1) event, so does NOT illustrate independent events.

The mean is the average. You calculate it by adding all the numbers up in the data set and divide by how many numbers there are in the data set.

So:

$\sf Mean=\dfrac{70+68+72+66+68+69+66+71+74+66}{10}\rightarrow\dfrac{690}{10}\rightarrow\boxed{\sf 69}$

Answer:

$75$ cubic inches

Step-by-step explanation:

Given:

The base of each pyramid is a square with a side length of 5 inches

Height of of pyramid is 9 inches.

To find: volume of the pyramid

Solution:

As the base of each pyramid is a square with a side length of 5 inches,

length of the pyramid (l) = base of the pyramid (b) = 5 inches

Height of of pyramid (h) = 9 inches

Volume of the pyramid $(V)=\frac{lbh}{3}$

On putting values of l, b and h, we get

$V=\frac{5\times 5\times 9}{3}=75$ cubic inches
