The bounds for a discrete brownian walk is [-3, 4]. what is the probability that the escape happens at 4?

Akimi4 [234]

Using it's concept, there is a 0.125 = 12.5% probability that the escape happens at 4.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

Considering that the bounds for a discrete brownian walk is [-3, 4], the possible outcomes are:

-3, -2, -1, 0, 1, 2, 3, 4.

A escape at 4 is one outcome, hence the probability is given by:

p = 1/8 = 0.125.

0.125 = 12.5% probability that the escape happens at 4.

Farmer bob's square plot ofland is slowly eroding away. Worried about the future of his farm. Farmer Bob measures the rate of er

kow [346]

Answer:

Option A.

Step-by-step explanation:

Area of a square is

$A=x^2$ .... (1)

where, x is side length.

The length of each side of his square plot is decreasing at the constant rate of 2 feet/year.

$\dfrac{dx}{dt}=2$

It is given that bob currently owns 250,000 square feet of land.

Fist find the length of each side.

$A=250000$

$x^2=250000$

Taking square root on both sides.

$x=500$

Differentiate with respect to t.

$\dfrac{dA}{dt}=2x\dfrac{dx}{dt}$

Substitute x=500 and $\frac{dx}{dt}=2$ in the above equation.

$\dfrac{dA}{dt}=2(500)(2)$

$\dfrac{dA}{dt}=2000$

Farmer bob is losing 2,000 square feet of land per year.

Therefore, the correct option is A.
