Answer:

Step-by-step explanation:
Given
Density = 3 starts in 10 cubic light years.
Required
Determine the probability of 1 or more in 10 cubic light years
Since the number of stars follow a Poisson distribution, we make use of:




T = the light years

Calculating

In probability:

Calculating P(X=0)
Substitute 0 for k and the values for
and T in








Substitute 0.04979 for P(X=0) in



--- approximated
Hence, the required probability is 0.9502
