rosijanka [135]

Answer:

The required probability is $\frac{14}{33}$ .

Step-by-step explanation:

Probability:

The ratio of the favorable outcomes to the all possible outcomes.

Given that, 5 women and 7 men are eligible to serve on a committee.

A committee of 4 is randomly selected.

Choosing 2 women out of 5 women is

$=^5C_2$

$=\frac{5!}{2!(5-2)!}$

$=\frac{5!}{2!3!}$

=10

Choosing 2 men out of 7 men is

$=^7C_2$

$=\frac{7!}{2!(7-2)!}$

$=\frac{7!}{2!5!}$

=21

Total number of eligible person is = (5+7)=12

Choosing 4 member out of 12 member is

= $^{12}C_4$

$=\frac{12!}{4!(12-4)!}$

=495

The required probability is

$=\frac{10\times 21}{495}$

$=\frac{14}{33}$

Answer plz...solve this sum n help me

tamaranim1 [39]

Answer:

28.57 m²

Step-by-step explanation:

Use rational terms.

$\frac{\frac{7}{9} }{200} =\frac{\frac{1}{9} }{x}$

Cross multiply:

7/9 · x = 1/9 · 200

7/9x = 200/9

x = 200/9 ÷ 7/9

x = 200/9 × 9/7

x = 200 · 9 / 9 · 7

x = 200 / 7

x = 28.57 m
