Consider the given density curve.
alisha [4.7K]

The Median of the density is -6.

An illustration of a numerical distribution with continuous results is a density curve. A density curve is, in other words, the graph of a continuous distribution. This implies that density curves can represent continuous quantities like time and weight rather than discrete events like rolling a die (which would be discrete). As seen by the bell-shaped "normal distribution," density curves either lie above or on a horizontal line (one of the most common density curves).

It is clearly visible from the uniform density curve given in the question that the median of the population density is  -6.
Because the area to the left and right of the density curve is the same.

Hence, the Median of density is -6.

Answer:

P(B and D) = 0.35

Step-by-step explanation:

It is a probability tree diagram. Here to find P(B and D):

apply method:

P(A and B) = P(A) × P(B)

Here given:

  • P(B) = .5
  • P(D) = .7

So, P(B and D):

  • P(B) × P(D)
  • .5 × .7
  • .35 ≈ 0.35
