Question

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

Answer 1

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{?} = ((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 * 4 = 56`

So this means the probability is

`(56)/(300) = (14)/(75)`

Which is 19%

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

`6 * 4 = 24`

So the probability

is

`(24)/(300) = (8)/(100) = (2)/(25)`

Which is equal to 8%
