Question

Javier simulated 100 classes of 30 students each, estimating the probability of having 7 or more left-handed students in a class. What is P(7or more left-handed) based on his results?

A. 0.08


B. 0.14


C. 0.28


D. 0.72

Answer 1

Javier simulated 100 classes of 30 students each and estimated the probability of having 7 or more left-handed students in a class. The probability is approximately 0.08.

Step-by-step explanation:

To estimate the probability of having 7 or more left-handed students in a class, Javier simulated 100 classes of 30 students each. Based on his results, we can calculate the probability using the binomial distribution formula. Since he simulated 100 classes, the probability of having 7 or more left-handed students in a class is the sum of the probabilities of having 7, 8, 9, ..., up to 30 left-handed students in a class. Using the binomial probability formula, we find that the probability is approximately 0.08 (option A).
