A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters. What is the probability of drawng a quarter, replacing it, and

rewona [7]

Given:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

To find:

The probability of drawing a quarter, replacing it, and drawing another quarter.

Solution:

A jar of coins has 8 pennies, 5 nickels, 1 dime, and 7 quarters.

Total number of coins = 8+5+1+7 = 21

Probability of getting a quarter is

$P(Quarter)=\dfrac{\text{Number of quarters}}{\text{Total number of coins}}$

$P(Quarter)=\dfrac{7}{21}$

$P(Quarter)=\dfrac{1}{3}$

After drawing a quarter, we replaced it. So, the probability of getting quarter in second draw is the same and first one, .i.e., $P(Quarter)=\dfrac{1}{3}$ .

The probability of drawing a quarter, replacing it, and drawing another quarter is

$P=\dfrac{1}{3}\times \dfrac{1}{3}$

$P=\dfrac{1}{9}$

Therefore, the required probability is $\dfrac{1}{9}$ .

Alex787 [66]

Answer:

There were 10 females and 14 males on the team.

Step-by-step explanation:

Step-1: Add the ratios.

5 + 7 = 12

Step-2: Divide it with the total number of students.

24 ÷ 12
=> 2

Step-3: Multiply.

5 x 2 = total females

7 x 2 = total males

=> 10 females
=> 14 males

Hence, there were 10 females and 14 males on the team.

The denominator of a fraction is 5 more than the numerator. if both the numerator and denominator are increased by 3, the the re

g100num [7]

Let's put it into perspective.

x/(x+5)

If increase by 3:

(x+3)/(x+8) = 3/4

Cross multiply.

4(x+3)=3(x+8)

4x+12 =3x+24

Solve algebraically.

4x-3x = 24-12

x = 12

Therefore, original fraction is:

12/17
