Geologists estimate the time since the most recent cooling of a mineral by counting the number of uranium fission tracks on the surface of the mineral. A certain mineral specimen is of such an age that there should be an average of 6 tracks per cm2 of surface area. Assume that the number of tracks in an area follows a Poisson distribution. Let X represent the number of tracks counted in 1 cm2 of surface area.
Compute P(X = 7). Round your answer to four decimal places.

0.1377 is the required probability.

Step-by-step explanation:

We are given the following information in the question:

The number of tracks in an area follow a Poisson distribution.

Mean number of track per area = 6 tracks per of surface area.

Formula:

We have to evaluate

P(x = 7)

0.1377 is the required probability.

answer: 4/6 =5/7.5

step-by-step explanation: it is based on scale and the scale between the two is 1.25. the answer is correct but i dont know if i explained it right
