Question

Let me see mathematics genius help me answer this question.​

Answer 1

Step-by-step explanation: Answer is

(i). 19% or 14/75

(ii) 28% or 7/25

We are asked to find multiple probabilities.

We got to find the number of combinations posible,

Use the combinations formula

$c {}^{n} _r{?} = \frac{(r + n - 1) \: fractorial).}{r \: fractorial(n - 1)fractorial}$

For math this is read as,

if n choose r,( r+n-1)!/r!(n-1)!.

Where r is how many things we need from and n is the number of things we choose from.

We need 2 things and we have 24 objects to pick from.

So r=2 N equal=24

Which equal

25!/2!(23)!

Which equals

$300$

So there are 300 possible combinations.

Using

For the 1st question, Since we are given two independent events, we can just multiply the number of good articles by major.

$14 \times 4 = 56$

So this means the probability is

$\frac{56}{300} = \frac{14}{75}$

Which is 19%

For the 2nd question, the can multiply the number of minor articles by major articles.

$6 \times 4 = 24$

So the probability

is

$\frac{24}{300} = \frac{8}{100} = \frac{2}{25}$

Which is equal to 8%
