4 cards. The probability of picking the 6 would be 1/4 ( 1 out of 4 cards)

After the first card is picked you have 3 cards left, 2 are less than 6, so you would have a 2/3 Probability.

The probability of both happening is:

1/4 x 2/3 = 2/12 = 1/6

The answer is 1/6

3. consider rolling a single die. we get the number d of the die. (10 points) a. if i tell you the number is less than 4 (d <

Semenov [28]

The probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

The probability of an event = The number of favorable outcomes to the event/The total number of possible outcomes.

In the question, we are asked to find the probability of getting an even number, considering rolling a single die, where we get the number d of the die, and the number is less than 4 (d < 4).

For the number d, the total number of possible outcomes, given d is less than 4 in the rolling of a single die is 3 {viz. 1, 2, and 3}.

For the event of getting an even number, from all the possible outcomes, the number of favorable outcomes is 1 {viz. 2}.

Thus, the probability of getting an even number, knowing that the number is less than 4, in the rolling of a single die is <u>1/3</u>.

As you might know from reading the Harry Potter books, wizarding money comes in three denominations: bronze Knuts, silver Sickle

Nina [5.8K]

Answer:

Minimun amount = $95,48

Step-by-step explanation:

We need to buy the book that costs 12 galleons, 16 sickles, 25 knuts.

At the bank we need to exchange our dollars. We know that:

1 galleon = $7,35

And:

1 galleon = 17 sickles

1 sickle = 29 knuts

First we use a rule of three to convert everything to galleons:

1 galleon = 17 sickles ⇒ 1 sickle = 1/17 galleons

$\frac{1 galleon}{x}=\frac{17 sickles}{1 sickle}$

$x=\frac{1}{17} sickles$

1 sickle = 1/17 galleons = 29 knuts ⇒ 1 knut = 1/493

$\frac{1/17 galleons}{x}=\frac{29 knuts}{1 knut}$

$x=\frac{1}{493} galleons$

And now we need to convert every wizarding money to dollars by using our reference above:

1 galleon = $7,35

1 sickle = 1/17 galleons = $7,35 / 17 ≅ $0,4323

1 knut = 1/493 galleons = $7,35 / 493 ≅ $0,0149

Finally we calculate the cost of the book:

Galleons: 12 x $7,35 = $88,2

Sickles: 16 x $0,4323 = $6,91

Knuts: 25 x $0,0149 = $0,37

Cost of the book = $88,2 + $6,91 + $0,37 = $95,48

So this is the minimun amount of dollars you need to exchange to purchase the book.
