Approximate the following binomial probability by the use of normal approximation. Twenty percent of students who finish high school do not go to college. What is the probability that in a sample of 80 high school students, 10 or less will not go to college? (Enter as a decimal rounding to 3 decimal places)

Title:

Step-by-step explanation:

It is given that, among 100 students, 20 students who finish high school, do not go to college.

Hence, the probability that a student will not go to school is .

We need to find the probability that 10 or less than 10 will not go to college.

The probability that all will go to college is .

The probability that only one will not go to college is .

Similarly, the probability of 10 or less than 10 will not go to college can be shown by ∑, where r = 0, 1, ....10.

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
