In a card game, there are
15
cards laid out on a table.
6
of the cards are blank,
2
of the cards are labeled
$3
, and the remaining cards are labeled
$1
. when you select a card at random, you earn what is labeled on the card. after each game, you return the card and the cards are shuffled. suppose you play this game
10
times. how much money can you expect to gain?

$130.

Step-by-step explanation:

The game has 15 cards:

6 cards are blank.

2 cards are $3.

7 cards are $1.

In one game, you can expect to gain:

6*$0 + 2*$3 + 7*$1 = $0 + $6 + $7 = 13$

If you play 10 times, then you can gain $13*10= $130

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
