I'm sorry, when I answered this I'm pretty sure I wasn't in algebra two yet. The correct answer is 4/52 * 3/51 = 1/221

On Saturday 1/8 of people who visited were senior citizen and 1/8 for infants 1/4 were children and 1/2 were adults how many of

vaieri [72.5K]

Answer:

$4,012\ senior\ citizen$

$4,012\ infants$

$8,024\ children$

$16,048\ adults$

Step-by-step explanation:

The complete question is

On Saturday,1/8 of the people who visited were senior citizens,1/8 were infants,1/4 were children,and 1/2 were adults.How many of each group visited the zoo on Saturday? It's has to equal to 32,096 people

we know that

1/8 of people were senior citizen

1/8 were infants

1/4 were children

1/2 were adults

To find out how many of each group visited the zoo on Saturday, multiply the total of people by the fraction of each group

$\frac{1}{8}(32,096)= 4,012\ senior\ citizen$

$\frac{1}{8}(32,096)= 4,012\ infants$

$\frac{1}{4}(32,096)= 8,024\ children$

$\frac{1}{2}(32,096)= 16,048\ adults$

Verify

The sum of the total of each group must be equal to 32,096 people

$4,012+4,012+8,024+16,048=32,096\ people$ ----> is correct

What is the probability that she chose the four students so that exactly ONE of them is a junior?

8090 [49]

Answer:

B) 0.246

Step-by-step explanation:

The desired probability is the sum of the probabilities of each of the ways one junior can be chosen. If we let a, b, c, d represent the ratio of juniors in classes 1 to 4, then this probability is ...

p(1 junior) = (a)(1-b)(1-c)(1-d) + (1-a)(b)(1-c)(1-d) + (1-a)(1-b)(c)(1-d) + (1-a)(1-b)(1-c)(1-d)

We can simplify this a little bit to ...

p(1 junior) = (1-a)(1-b)(1-c)(1-d) × (a/(1-a) +b/(1-b) +c/(1-c) +d/(1-d))

___

So, for {a, b, c, d} = {9/15, 12/15, 6/15, 3/15} = {3/5, 4/5, 2/5, 1/5} the probability of interest is ...

p(1 junior) = (2/5·1/5·3/5·4/5) × (3/2 + 4/1 + 2/3 + 1/4) = 24/625 × 77/12

p(1 junior) = 154/625 ≈ 0.246

_____

Comment on the sum we're computing

Each of the probabilities in the first sum above is ...

p(junior in given class) · p(not a junior in the other 3 classes)
