Your personal library contains books written by 165 authors. 60% of the authors are men. 40% of the authors write only nonfictio

Ludmilka [50]

Lets discern the infomation:

number_men = 165*0.6 = 99

so there are 99 men

non_fiction = 165 * 0.4 = 66

so 66 authors write non-fiction.

men writing non-fiction are 40, so 59 men write fiction, and 26 women write non-fiction.

probability of author non-fiction or man?
non-fiction: 40 men + 26 women = 66 total
man writers = 99

so in total 99 man + 26 women = 115 authors

hence the probability is:
115/165 = 69.6%

Use braces and digits to designate the set of natural numbers.

alina1380 [7]

Answer:

$N = \{1,2,3,4,5,6,.....\}$

Step-by-step explanation:

Required

Determine the sets of natural number

Represent this set with letter N

From definition of natural numbers, they are integer numbers starting from 1;

In other words: 1,2,3,4,5, and so on.

To represent this as a set of N, we have

$N = \{1,2,3,4,5,6,.....\}$

<em>The ..... means that the counting still continues</em>
