Question

Assume that when adults with smartphones are randomly​ selected, 42​% use them in meetings or classes. If 6 adult smartphone users are randomly​ selected, find the probability that at least 2 of them use their smartphones in meetings or classes.

Answer 1

Okay I'm going to make an attempt, using Google and a reference problem that I found:

Answer 2

To find the probability that at least 2 out of 6 adult smartphone users use their smartphones in meetings or classes, we first find the probability that fewer than 2 use their smartphones in meetings or classes. This involves calculating the probability of 0 users and 1 user. Then, we subtract the combined probability of these events from 1 to get the probability that at least 2 people use their smartphones in meetings or classes. This approach ensures we cover all possible outcomes and obtain the desired probability.
