Answer:
The probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
Step-by-step explanation:
Let <em>X</em> = number of adults who use smartphones in meetings or classes.
The probability of the random variable <em>X</em> is, P(X) = <em>p</em> = 0.42
A sample of <em>n</em> = 5 adult smartphone users are selected.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The probability mass function of <em>X</em> is:
Compute the value of P (X = 2) as follows:
Thus, the probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
