Submit teFor the experiment of drawing a single card from a standard 52-card deck, find (a) the probability, and (b) the odds in

Studentka2010 [4]

QUESTION A

The probability of an event is calculated using the formula:

$P(E)=\frac{Number\text{ }of\text{ }favorable\text{ }outcomes}{Number\text{ }of\text{ }possible\text{ }outcomes}$

There are 4 nines in a standard deck of cards. Therefore, there are 48 cards that are not nines.

Since there are 52 cards, the probability is calculated to be:

$\begin{gathered} P=\frac{48}{52} \\ P=\frac{12}{13} \end{gathered}$

The probability is 12/13.

QUESTION B

Odds in favor of a particular event are given by the number of favorable outcomes to the number of unfavorable outcomes. The formula is written out to be:

$P(E)=\frac{Number\text{ }of\text{ }favorable\text{ }outcomes}{Number\text{ }of\text{ }unfavorable\text{ }outcomes}$

Since we have that the number of favorable outcomes is 48 and the number of unfavorable outcomes is 4, we have that the odds in favor are given to be:

$P=\frac{48}{4}=\frac{12}{1}$

The odds are 12 to 1.

Answer:

66 $cm^{3}$

Step-by-step explanation:

Vol = Bh where B is the area of the base and h is the distance between the bases (height)

The base is a right triangle and has an area of

B = 1/2bh = 1/2(4)(3) = 6

h = 11

V = 6(11) = 66 $cm^{3}$

A box contains 16 cherry fruit chews, 15 peach fruit chews, and 12 Plumford choose. Which two flavors are in the ratio 5 to 4?

Kipish [7]

A couple of different ways to solve this.

Build ratio 5/4
Multiply by 2/2 to get equivalent, which is 10/8 - this does not match any possible solution.
Now do 5/4 * 3/3 to get 15/12. This works, so the answer is 15 peach fruit chews/12 plumb fruit chews.

Trial and error method.
