Which of the following is an example of independent events?
Zolol [24]
The correct answer is Choice B because each of these events are separate items.  Each of the others choices will have a part of the additional events that are affected by the first event.  When the first event happens in each of these options, the second event's probability is affected by the first outcome.  The number of total outcomes changes because of the first event in all choices, except for choice B.

Katie had 4 full cement blocks and one that was 4⁄6 the normal size. If each full block weighed 3 2⁄4 pounds, what is the weight
sveta [45]

Answer:

The weight of the block that Katie has is 16 1/3 pounds

Step-by-step explanation:

<u>Katie has: 4 full cement blocks and 4/6 (or 2/3 ) of the normal size of a cement block</u>

For one full block, it weighs 3 2/4 ( or 1/2) pounds, if you want to find the answer of the question, you need to multiply the weight with the cement blocks that Katie have.

<u>First do the four full cement blocks:</u>

4 * 3 2/4 = ?

4 * 14/4 = ?

Cancel the 4 that is being multiplied and the 4 that is being divided by 14.

= 14.

<u>Now do the 4/6 (or 2/3) cement block:</u>

2/3 * 3 2/4 = ?

2/3 * 14/4 = ?

Multiply the fractions together:

= 28/12

= 2 1/3

<u>Finally, you add up the full blocks and the 2/3 cement block to get your answer:</u>

2 1/3 + 14 = 16 1/3

The weight of the block that Katie has is 16 1/3 pounds
