The number of absences for one week for all students at a high school were compiled, and the probability distribution below was created. What is the probability in any given week that a randomly selected student will be absent no more than one day? Probability Distribution Days Absent: X Probability: P(X) 0 0.78 1 0.14 2 0.03 3 0.01 4 0 5 0.04 0.08 0.14 0.78 0.92

Answer:

Option D) 0.92

Explanation:

We are given the following probability distribution in the question:

x: 0 1 2 3 4 5

P(X): 0.78 0.14 0.03 0.01 0 0.04

We have to find the probability that a randomly selected student will be absent no more than one day.

Thus, we have to evaluate:


P(x\leq1)\\=P(X=0) + P(X = 1)\\=0.78 + 0.14\\=0.92

0.92 is the probability that a randomly selected student will be absent no more than one day.

Thus, the correct answer is

Option D) 0.92
