The total possibilities can be 756 ways.
<h3>What is combination?</h3>
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.
Given:
The number of ways in which we can select atleast 3 men in the committee are 756.
Number of men = 7
Number of women = 6
Number of people that should be selected in the committee = 5
Now,
N(M = 3) = 7C_3* 6C_2
=35*15
=525
N(M = 4) = 7C_4* 6C_1
=35*6
=210
N(M = 3) = 7C_5* 6C_0
=21*1
=21
So, total possibilities can be = 525 + 210 + 21 = 756 ways.

use cross products to solve
5* (n-9) = 8*n
distribute
5n-45 = 8n
subtract 5n from both sides
-45 = 3n
divide both sides by 3
-15 = n
Answer:
i unfortunately dont understand this language
H=height of ostrich
k=height of kiwi
h is 20 more than 4 times k
k=20+4k
k=108
108=20+4k
minus 20 from both sides
88=4k
divide both sides by 4
22=k
answer is A
