A contestant’s final winnings on a game show are determined by a random selection of a base amount and a possible multiplier. Fo

r the base amount, the contestant randomly selects one of four cards, where two cards are marked $1,000, one card is marked $2,000, and one card is marked $5,000. After choosing the card, the contestant randomly selects one of five chips, where three chips are red and two chips are white. If the selected chip is red, the contestant’s final winnings are twice the value of the base amount. If the selected chip is white, the contestant’s final winnings are the value of the base amount. What is the probability that a contestant’s final winnings are exactly $2,000?

Answer:

\frac{8}{25} = 0.32

Step-by-step explanation:

Exactly $2000 final winnings is possible only in <em>one of the following two cases</em>:

1)

<em>The chosen card is marked $1000 and then red chip is selected.</em> Because red chip doubles contestant's $1000 base amount, and makes it $2000.  

  • Since two cards of the five cards are marked $1000, the probability of choosing $1000 marked card is \frac{2}{5}
  • Since three of five chips is red, the probability of choosing red chips is \frac{3}{5}

Then the probability of both choosing $1000 marked card and red chip is:

\frac{2}{5} × \frac{3}{5} = \frac{6}{25}

2)

<em>The chosen card is marked $2000 and then white chip is selected.</em> Because white chip makes the contestant's final winning remain the same as base amount, which is $2000

  • Since one card of the five cards are marked $2000, the probability of choosing $2000 marked card is \frac{1}{5}
  • Since two of five chips is white, the probability of choosing red chips is \frac{2}{5}

Then the probability of both choosing $2000 marked card and white chip is:

\frac{1}{5} × \frac{2}{5} = \frac{2}{25}

The probability that a contestant's final winning is the sum of probabilities of these two cases:

\frac{6}{25} × \frac{2}{25} = \frac{8}{25}= 0.32

Dahasolnce [82]

Answer:

386 passengers arrive at Estados Unidos.

386 pasajeros aterrizará en Estados Unidos.

Step-by-step explanation:

English Translation

A plane from Córdoba bound for Estados Unidos and makes stops in Chile and Bolivia. The plane has a capacity for 507 passengers. He leaves the Córdoba airport with 119 empty seats. In Chile 33 passengers go down and 121 go up. In Bolivia 129 go down and 39 go up. How many arrive in Estados Unidos?

- The plane has capacity for 507 passengers.

- 119 seats are empty when it leaves Córdoba.

Meaning that there were (507 - 119) passengers on board = 388 passengers

- In Chile 33 passengers go down and 121 go up.

Number of passenger become

388 - 33 + 121 = 476 passengers

- In Bolivia 129 go down and 39 go up.

Number of passengers become

476 - 129 + 39 = 386 passengers.

A number is 5 more than 3 times another number. The sum of the two numbers is 33. As an equation, this is written x + 3x + 5 = 3
Cloud [144]

Answer:

x=7, so the smaller number is 7 and the larger number is 21.

Step-by-step explanation:

x=3x+5=33

Let x=3:

(3)+3(3)+5=3+9+5=17, not 33, so x is not 3

Let x=5:

(5)+3(5)+5=5+15+5=25, not 33, so x is not 5

Let x=7:

(7)+3(7)+5=7+21+5=33, so x=7

Let x=9:

(9)+3(9)+5=9+27+5=41, not 33, so x is not 9

Therefore x=7. Because x represents the smaller number, and the larger number is 3 times the smaller number, the smaller number is 7 and the larger number is 3(7)=21.
