Answer:

Option (D) : 1 / 4

Step-by-step explanation:

We know that :

P(A ∩ B) = P(A) * P(B|A)

P(B|A) = P(A ∩ B) / P(A) =  \frac{13}{25}  \times  \frac{20}{13}

P(B|A) =  \frac{4}{5}

maks197457 [2]

Answer:

if youre answer has to be a whole number it would be 3 otherwise it would be  x<4 ( so anything less than 4 )

Step-by-step explanation:

so because we are trying to find which company is less, we need to set up in inequality.

so first lets do company A

because 15 is our reoccuring fee, its going to be the coeifficient

so the equation would be

A - 15x + 20

now lets do company B

because it only 20 every month we dont need to have a constant which means the equation for B would be

B - 20x

so lets put it all together

15x + 20 > 20x ( remember our B side has to be less )

now lets solve it

20 > 5x

we know that if x = 4 then the two would be equal, which means our answer would have to be 3 months.

now always check your work.

15 (3) + 20 = 65

20(3) = 60
