In how many ways can a subcommittee of 6 students be chosen from a committee which consists of 10 senior members and 12 junior members if the team must consist of 4 senior members and 2 junior members?

Answers

Answer:

The number of ways is 13860 ways

Step-by-step explanation:

Given

Senior Members = 10

Junior Members = 12

Required

Number of ways of selecting 6 students students

The question lay emphasis on the keyword selection; this implies combination

From the question, we understand that

4 students are to be selected from senior members while 2 from junior members;

The number of ways is calculated as thus;

Ways = Ways of Selecting Senior Members * Ways of Selecting Junior Members

$Ways = ^(10)C_4 * ^(12)C2$

$Ways = (10!)/((10-4)!4!)) * (12!)/((12-2)!2!))$

$Ways = (10!)/((6)!4!)) * (12!)/((10)!2!))$

$Ways = (10 * 9 * 8 * 7 *6!)/((6! * 4*3*2*1)) * (12*11*10!)/((10!*2*1))$

$Ways = (10 * 9 * 8 * 7)/(4*3*2*1) * (12*11)/(2*1)$

$Ways = (5040)/(24) * (132)/(2)$

$Ways = 210 * 66$

$Ways = 13860$

Hence, the number of ways is 13860 ways

If there are 16 ounces in a pound how manyh are in 24 ounces

Answers

16 ounces = 1 pound

Explanation:

Your question is related to unit conversion. If we know that one pound equals 16 ounces, then to convert 24 ounces to pounds, we must divide 24 ounces by the number of ounces in a pound. Here's how we can do it:

Set up the conversion: 24 oz / 16 oz/lb.
Dividing these amounts gives the result: 24 / 16 = 1.5 lbs.

S, this means that 24 ounces is equal to 1.5 pounds.
