Assume that when adults with smartphones are randomly selected, 51% use them in meetings or classes. If 10 adult smartphone users are randomly selected, find the probability that fewer than 4 of them use their smartphones in meetings or classes.
This is required solution for this problem. Hope it will help you.
Here calculation has done with the help of calculator. Please like and give a Thumbs up to keep motivate me. Thank you ?
