In the game of blackjack played with one deck, a player is initially dealt 2 different cards from the 52 different cards in the

Volgvan

Answer:

$P =4.83\%$

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

$nCr=\frac{n!}{r!(n-r)!}$

Where n is the total number of letters and r are chosen from them

The number of ways to choose 1 As is:

$4C1 = 4$

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

$16C1 = 16$

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

$4C1 * 16C1 = 4 * 16 = 64$

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

$52C2 =\frac{52!}{2!(52-2)!}$

$52C2 = 1326$

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

$P = \frac{4C1 * 16C1}{52C2}$

$P = \frac{64}{1326}$

$P = \frac{32}{663}$

$P =0.0483$

$P =4.83\%$

Why do test makers refer to the first term in a sequence as a sub zero sometimes as opposed to a sub 1?

Kaylis [27]

The first term in a sequence is sometimes referred to as $a_0$ as opposed to $a_1$ because $a_0$ represents the initial value

<h3>How to explain the sequence statement?</h3>

The question refers to the difference between the terms

$a_o$ and $a_1$

The terms in a sequence are represented by a subscript number.

Take for instance a₂ or T₂ represents the second term.

However, when the first term is represented by a₀ instead of a₁.

It means that the sequence has an initial value, other than the first term.

Even though the words "first" and "initial" are synonyms, they do not entirely represent the same thing.

Take for instance, a₀ can be used instead of a₁ in the following scenario

<em>The population of a country is 1000 in 1996 and The country experiences an increment of 250 people every year after 1996.</em>

<em />

The above means that:

a₀ = 1000 --- the initial year

a₁ = 1000 + 250 = 1250 ---- the first year after 1996 (i.e. 1997)
