The board of directors of a corporation must select a president a secretary and a treasurer in how many possible ways can this b

Anika [276]

There are 9240 possible ways in which a president, a secretary and a treasurer can be selected from the 22 members on the board of directors.

<h3><u>Solution:</u></h3>

Give that the board of directors of a corporation must select a president a secretary and a treasurer.

Need to calculate in how many possible ways this can be accomplished if there are 22 members on the board of directors

Here we are assuming that one person can hold only one position means one if get selected for president he is out of the race for remaining positions that are secretary and treasure

Lets for sake of understanding, we simplify our question.

Lets say there are 3 members A , B and C . In how many ways two positions of Secretary and treasurer can be filled .

So for selecting secretary we have three option that are A , B or C.

And once secretary is selected , number of option for selecting treasure is two.

So it is found that number of selecting 2 positions for 3 members is product of option available for selecting first position that is secretary multiplied by option available for selecting second position that is treasurer = 3 x 2 = 6

So now applying same logic for selecting members for 3 positions from 22 menbers we get

For selecting president members available = 22

Once president is selected, then option available for selecting a Secretary = 21

And one secretary is also selected, then option available for selecting a treasure = 20

So number of ways in which three positions can be filled by 22 member = 22 x 21 x 20 = 9240

Hence there are 9240 possible ways in which a president , a secretary and a treasurer can be selected from the 22 members on the board of directors.

if a tablet has the capacity of 22 GB. and for a plain textbook one bite typically corresponds to one character and an average p

kotykmax [81]

The tablet has a capacity of 22GB

one bite = 1 character

2000 characters = 1 bite x 2000 characters= 2000 bites

1 bite = 1 x 10^-9 giga bite

------- -----------------------

x bite = 22 giga bite

Cross multiplying

x bite = (22GB) / 1 x 10^-9 GB

x = 2.2 x 10^10 bites

To find how many pages of text the tablet holds we divide the value of 22GB in bites by the number of bites of one page

22GB = 2.2 x 10 ^10 bites

1 page holds 2000 bites

No of pages of text the tablet can hold = (2.2 x 10^10)/2000 = 11000000 pages of text

A 500 page book has 500 x 2000 characters = 1,000,000 characters

1000000 characters = 1000000 bites

The number of 500-page books the tablet can hold =

$\frac{2.2x10^{10}}{1000000}=22,000\text{ 500-page books}$

answer for the B part = 22,000 500-page books
