Answer:

The probability is 3/95

Step-by-step explanation:

Okay this is a probability without replacement question.

Firstly we calculate the total number of coins = 7 + 9 + 4 = 20 coins

The probability that the first coin will be a dimes = number of dimes/total number of coins = 4/20 = 1/5

Now she removes a coin without replacement, if it was a dime, total number of coins becomes 19 and the total number of dimes becomes 3; Thus the probability of the second coins being a dimes = 3/19

Thus, the probability of both coins being dimes = probability of first coin being dimes * probability of second coins being dimes

= 1/5 * 3/19 = 3/95

Answer:

Total dollars = 35 dollars.

Step-by-step explanation:

Number of cups = 8 cups

Number of gallons = 3 gallons

Price of soil per quart = $2.50

Now convert the cups and gallons into quart.

Total quart = 8 cups + 3 gallons

Total quart = 8 / 4 quart + 3 x 4 quarts

Total quart = 2 quart + 12 quart

Total quart = 14 quart

Total dollars amount = $2.50 per quart x 14 quart

Total dollars = 35 dollars.

Data

Number of employees = 192

See the table

Process

a) To solve this question, consider only the employees that prefer a jacket

          Male        77

          Female  +35

                         112 employees prefer a jacket

- Calculate the probability

            P = 112 / 192

            P = 0.58

b) Female and prefers a jacket

            P = (54 /192)(35/192)

            P = (0.28)(0.18)

            P = 0.05
