There are 12 coins in the bag. For the first case, the probability that a penny is selected from the bag is 5/12 because there are 5 pennies in the bag. Also, the next one is 3/11. Multiplying the probabilities,
                           (5/12)(3/11) = 8/121

Answer:

Part One: $187

Part Two: 11a + 5.5k

Step-by-step explanation:

Part One:

a = 9 (how many adult tickets)

k = 16 (how many kid tickets)

($11 × a) + ($5.50 × k) = total cost

($11 × 9) + ($5.50 × 16)

($99) + ($88) = $187 = total cost

Part Two:

11a + 5.5k

11 is how much the adult ticket costs, you multiply a or the amount of adult tickets in order to get the total cost for adults.

5.5 is how much the kid ticket costs, you multiply k or the amount of kid tickets in order to get the total cost for kids.

you add 11a + 5.5k or the total cost for adults and the total cost for kids to get the total cost.

A soccer team wins 65% of its matches, and 15% of its matches end in a draw. If the team is scheduled to play 20 matches, about
STatiana [176]

Answer:  There are 4 matches that are expected to lose by a soccer team.

Step-by-step explanation:

Since we have given that

Probability that a soccer team wins = 65%

Probability that a soccer team ends in a draw = 15%

Total probability we get

65\%+15\%=80\%

Probability that matches are expected to lose is given by

100\%-80\%=20\%

Since number of matches is scheduled to play = 20

Number of matches expected to lose is given by

\frac{20}{100}\times 20\\\\=\frac{400}{100}\\\\=4

Hence, there are 4 matches that are expected to lose by a soccer team.
