<h3>Answer:  0.85  (Choice A)</h3>

===========================================================

Explanation:

x = number of siblings

We add the probability values that correspond to x = 0 and x = 1, which is when the person has 0 siblings and 1 sibling respectively.

Those probabilities are: 0.20 and 0.65

So we get 0.20+0.65 = 0.85

There's an 85% chance of randomly picking someone who has fewer than two siblings.

A computer’s memory is composed of 8k words of 32 bits each. how many total bytes in memory?
Mandarinka [93]

The number of total bytes in memory is 32,000 bytes.

<h3>How many total bytes in memory?</h3>

We know that the memory is composed of 8k (or 8,000) words of 32 bits each.

To get the total memory, we just need to take the product between the number of words and the memory that each has.

This will give:

8,000*(32 bits) = 256,000 bits.

But we want this in bytes so we need to change the units, remember that:

1 bit = 0.125 byte.

Then we have:

256,000 bits = 256,000*( 0.125 byte) = 32,000 bytes.

The memory has 32,000 bytes in total.
