Answer:

15

Step-by-step explanation:

Given that there are 6 people in a raffle drawing. Of these 6, two win raffle cards and both gift cards are identical.

SInce here order in which person receive gift does not matter, combinations is the way we have to calculate.

Out of 6 persons we have to find the number of ways of 2 persons receiving gift cards.

No of ways = 6C2 =6(5)/2\\=15

Hence correct answer is Option B

Answer:

Combination; number of ways = 15.

Step-by-step explanation:

Given that there are 6 people in the contest. So it means n = 6.

Two winners each win gift cards. So it means r = 2.

Each gift card is same, so both persons are equally important. It means the order does not matter here, so it is the case of Combinations. We will use nCr formula.

Total number of ways = 6C2 = (6*5)/2 = 15.

Hence, Combination; number of ways = 15.

nata0808 [166]

The complete question is

"The cafeteria staff made sandwiches. Each sandwich had either rye or white bread, either ham or turkey, and either cheese or no cheese. The staff made an equal number of each type of sandwich.

The sandwiches were placed on a tray. Without looking, Mary will choose a sandwich.

What are the chances that Mary will get a sandwich with cheese?"

The chances of Mary getting a sandwich with cheese is 1/2.

<h3>How to calculate the number of different ways?</h3>

The number of different sandwiches is calculated by multiplying all of the possibilities for each material being used.

rye or white bread: 2 options

ham or turkey: 2 options

cheese or no cheese: 2 options

So the number of different sandwiches = 2*2*2 = 8.

4 have cheese and 4 have no cheese, as the staff made an equal number of each type of sandwich.

So, The chances of Mary getting a sandwich with cheese is 4/8 = 1/2.

A plane traveled 2565 miles with the wind in 4.5 hours and 2205 miles against the wind in the same amount of time. Find the spee
kherson [118]

Answer:

  • plane: 530 mi/h
  • wind: 40 mi/h

Step-by-step explanation:

Let p and w represent the speeds of the plane and the wind. The relation between time, speed, and distance is ...

  speed = distance/time

  p +w = (2565 mi)/(4.5 h) = 570 mi/h

  p -w = (2205 mi)/(4.5 h) = 490 mi/h

Adding these speeds, we get ...

  (p +w) +(p -w) = (570) +(490) mi/h

  2p = 1060 mi/h

  p = 530 mi/h

Then the speed of the wind is ...

  w = 570 mi/h -p = (570 -530) mi/h = 40 mi/h

The plane's speed is 530 mi/h; the wind speed is 40 mi/h.
