3/4 of the bat blood was used = 18/24 most Ethel
2/3 of the knotgrass was used= 16/24 more Locasta
1/2 of the moonstone was used=12/24 less Circe
3/8 of the unicorn hair was used=9/24 least Glinda

Circe used the moonstone

Using probability concepts, it is found that:

a) $\frac{4}{13}$ probability of drawing a card below a 6.

b) $\frac{4}{9}$ odds of drawing a card below a 6.

c) We should expect to draw a card below 6 about 4 times out of 13 attempts, which as an odd, it also 4 times for every 9 times we draw a card above 6, which is the third option.

------------------------------

A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.

Item a:

In a standard deck, there are 52 cards.
There are 4 types of cards, each numbered 1 to 13. Thus, $4 \times 5 = 20$ are less than 6.

Then:

$p = \frac{20}{52} = \frac{4}{13}$

$\frac{4}{13}$ probability of drawing a card below a 6.

Item b:

Converting from probability to odd, it is:

$\frac{4}{13 - 4} = \frac{4}{9}$

$\frac{4}{9}$ odds of drawing a card below a 6.

Item c:

The law of large numbers states that with a <u>large number of trials, the percentage of each outcome is close to it's theoretical probability.</u>
Thus, we should expect to draw a card below 6 about 4 times out of 13 attempts, which as an odd, it also 4 times for every 9 times we draw a card above 6, which is the third option.

Joe's Ice Cream Shop has 7/8 of a gallon of vanilla ice cream left. They use 1/12 of a gallon of ice cream to make one milkshake

Vadim26 [7]

Answer:

Ten and a Half milkshakes can be prepared from the available amount of ice cream.

Step-by-step explanation:

The total vanilla ice cream = 7/8 gallons

Ice cream used for 1 milkshake = 1/12 gallon

Now, total number of milkshakes possible = $\frac{\textrm{Total availibility of ice cream}}{\textrm{Ice cream used for each milkshake}}$
