A bag contains 2 black balls, 4 yellow balls and 4 white balls. Event A is defined as drawing a white ball on the first draw and event B is defined as drawing a black ball on the second draw. If two balls are drawn from the bag, one after the other and not replaced, what is P(B|A) expressed in simplest form? A. B. C. D.

Answers

Answer 1

Answer: [tex]P(B|A)=\dfrac{4}{9}[/tex]

Step-by-step explanation:

Given: A bag contains 2 black balls, 4 yellow balls and 4 white balls.

Event A is defined as drawing a white ball on the first draw.

Event B is defined as drawing a black ball on the second draw.

P(B|A) is expressed as the conditional probability of occurring B given that A.

i.e. it is the probability of happening B where A is already happended.

If a white ball is drawn at first, then the number of black ball(4) remains unchanged but the total number of balls (10) will become 9.

[tex]Probability=\dfrac{Number\ of \ favorable \ outcomes}{Total\ outcomes}[/tex]

Then, [tex]P(B|A)=\dfrac{4}{9}[/tex]

Answers

Answer:

The ratio of juices to ginger ale is 2 to 2

The ratio of orange juice to the cranberry juice is 1 to 1

Step-by-step explanation:

Ginger ale = 2 liters

Orange juice = 1 liter

Cranberry juice = 1 liter

Total ratio = 2 + 1 + 1 = 4

The ratio of ginger ale to the entire punch bowl is 1 to 4.

Ginger ale : entire punch bowl

= 2 : 4

Not true

The ratio of orange juice to ginger ale is 2 to 1.

Orange juice : ginger ale = 1 : 2

Not true

The ratio of juices to ginger ale is 2 to 2.

juices : ginger ale = orange juice + cranberry juice : ginger ale

= 1 + 1 : 2

= 2 : 2

The ratio of the entire punch bowl to the juices is 2 to 4.

Entire punch bowl : juices 4 : 2

Not true

The ratio of orange juice to the cranberry juice is 1 to 1.

Sturdy’s paper plates cost $3.12 for 24 plates. Tough’s paper plates cost $4.32 for 32 plates. Which is the better buy?

Answers

Answer:

Sturdy's paper plates

Step-by-step explanation:

Let's see how much 8 plates cost:

Sturdy

24/3=8

$3.12/3= $1.04

Tough

32/4=8

$4.32/4=$1.08

$1.04<$1.08

Because Tough's paper plates costs 4 cents more for 8 plates, Sturdy's paper plates are the better buy.
