Short Answer

Expert verified

The probability that a Physics major will undertake post-graduate study forxyears is defined asP(x).

Step by step solution

01

Given Information

A physics teacher likes to know what percentage of physics students will undertake post-graduate study in the coming years. He is in knowledge of the following probability distribution:

02

Explanation

P(x)is defined as the probability that Physics major does post-graduate study for xnumber of years. By looking at the table we can say that probability that Physics major student will do post graduate for1year is 0.352years is 0.20and so on.
