Answer:

Results:

0.1432

0.0045

0.0905

0.0483

Step-by-step explanation:

Step a:

P(A or 10, A or 10) = 20/52 * 19/51 = 5/13 / 19/51 = 95/663 = 0.1432

Step b:

P(A A) = 4/52 * 3/51 = 1/13 * 1/17 = 1/221 = 0.0045

Step c:

P(10 10) = 16/52 * 15/51 = 4/13 * 5/17 = 20/221 = 0.0905

Step d:

P(A 10 or 10 A) = 2 * 4/52 * 16/51 = 2/13 * 16/51 = 32/663 = 0.0483

As well we get the probability by subtracting a, b and c:

P(blackjack): 0.1432 - 0.0905 - 0.0045 = 0.0482

Future value with annuity:

The future value formula, for an annuity, is:

$FV = \frac{P((1+r)^{n} - 1)}{r}$

An annuity means that a number of payments happen during the period(an year, for example.

P is the value of the deposit, r is the interest rate, as a decimal, and n is the number of deposits.

In this question:

1000 € each year, so $P = 1000$

Interest rate of 6%, so $r = 0.06$

One application per year for 8 years, so $n = 8$

Total amount:

$FV = \frac{1000((1+0.06)^{8} - 1)}{0.06} = 9897.47$

There will be 9897.47€ in the account.

La cantidad será de 9897.47€.
