4x = 8x − 1<br><br> x = three fourths<br> x = 1<br> x = 3<br> x = 6
makvit [3.9K]
Isolate the variable by subtracting 8x from both sides to get -4x = -1. multiply both sides by -1 to get 4x = 1. divide both sides by 4 to get x = 1/4.

If A and B are independent events and P(A)=0.25 and P(B)=0.333, what is the probability P(ANB)?
Pachacha [2.7K]

The probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is <u>0.08325</u>. Hence, <u>option C</u> is the right choice.

For any two events A and B, the probability of event A and B, that is, P(A ∩ B) is given as:-

  1. When the events are dependent, P(A ∩ B) = P(A).P(B|A).
  2. When the events are independent, P(A ∩ B) = P(A).P(B).

In the question, we asked the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333.

We know that when the events are independent, P(A ∩ B) = P(A).P(B).

Thus, P(A ∩ B) = (0.25)*(0.333),

or, P(A ∩ B) = 0.08325.

Thus, the probability P(ANB), that is, P(A ∩ B), given that A and B are independent events and P(A) = 0.25 and P(B) = 0.333 is <u>0.08325</u>. Hence, <u>option C</u> is the right choice.

Pablo guarda en su cajon 2 pares de medias blancas 4 pares de medias de azules y tres pares de medias negras cual es la probabil
RUDIKE [14]

Answer:

44.4%

Step-by-step explanation:

The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:

We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.

therefore the probability is:

4/9 = 0.444

Which means that there is a 44.4% chance of drawing a blue pair.
