Answer:

Step-by-step explanation:
First we calculate the number of possible ways to select 2 cards an ace and a card of 10 points.
There are 4 ace in the deck
There are 16 cards of 10 points in the deck
To make this calculation we use the formula of combinations

Where n is the total number of letters and r are chosen from them
The number of ways to choose 1 As is:

The number of ways to choose a 10-point letter is:

Therefore, the number of ways to choose an Ace and a 10-point card is:

Now the number of ways to choose any 2 cards from a deck of 52 cards is:


Therefore, the probability of obtaining an "blackjack" is:





Let’s find the tax first:
$24 • 0.065 = $1.56
Now, add the tax to the price of the jeans.
$24 + $1.56 = $25.56
Hope this helps! :)
This expression is equal to (3*3)/(16*2), or 9/32.
The slope is 7 because the slope formula m = rise over run gets you there
