27x³ + 33x² - 15x + 4x³ + 22x - 10x² - 5x² + 8

Add like terms.

(27x³ + 4x³) + (33x² - 10x²) + (-15x + 22x) + 8

Simplify.

31x³ + 23x² - 7x + 8

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%
