Astronomers treat the number of stars in a given volume of space as a Poisson random variable. The density in the Milky Way Gala
umka21 [38]

Answer:

a) 0.264

b) 48 cubit light-years

Step-by-step explanation:

For calculating a)  What is the probability of 3 or more stars in 16 cubic light years?

a)

λ= 1 star/16 cubic light-years

t= measure t in units of 16 cubic light years.

E(Y) = λ t = (1/16)(16) = 1 star

P(X>=2) = 1 - P(X<2)

= 1 - [e^-1 + (e^-1)(1)/1!]

= 0.264

b)

P(X≥1) = 1 - P(X=0)

= 1 - e^-μ

0.95 = 1 - e^-μ

e^-μ = 1 - 0.95

e^-μ = 0.05

ln(e^-μ) = ln(0.05)

-μ = -3

μ = 3

Therefore  3 x 16 = 48 cubic light years of space

Can some one help me on this
wel

Answer:

480

Step-by-step explanation:

Find the difference between 2400 and 40 by dividing:

2400 / 40 = 60

Multiply each value by 60:

12 x 60 = 720 chocolate

15 x 60 = 900 caramel

5 x 60 = 300 banana

8 x 60 = 480 marshmallow
