Umm....where is the graph?
or is it just my computer????
Solution: The given random experiment follows Binomial distribution with 
Let
be the number of adults who use their smartphones in meetings or classes.
Therefore, we have to find:

We know the binomial model is:






Therefore, the probability that fewer than 3 of them is 0.1111
