Flura [38]

Answer:

55/2574 ≈ 2.18%

Step-by-step explanation:

There are a total of 13 people on the council.

The probability that the first person is a Democrat is 8/13.

The probability that the second person is a Democrat is 7/12.

The probability that the third person is a Republican is 5/11.

The probability that the fourth person is a Republican is 4/10.

The probability that the fifth person is a Republican is 3/9.

The total probability is:

P = (8/13) (7/12) (5/11) (4/10) (3/9)

P = 56/2574

P ≈ 0.0218

There is a 2.18% probability of selecting two Democrats and three Republicans.

Norma-Jean [14]

Answer:

The percentage decrease is 29%

Step-by-step explanation:

Given

$Initial = 300$

$Final = 213$

Required

Determine the percentage decrease

This is calculated as thus:

$\%Percentage = \frac{|Final - Initial |}{Initial} * 100\%$

Substitute values for Final and Initial

$\%Percentage = \frac{|213 - 300|}{300} * 100\%$

$\%Percentage = \frac{|-87|}{300} * 100\%$

<em>Get absolute value of -87</em>

$\%Percentage = \frac{87}{300} * 100\%$

$\%Percentage = \frac{87* 100\%}{300}$

$\%Percentage = \frac{8700\%}{300}$

$\%Percentage = 29\%$

Hence, the percentage decrease is 29%
