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.

Step-by-step explanation:
In triangle ABC, perpendiculars dropped on the sides AB and AC from the ray BD are equal in measure or congruent.
Therefore, ray BD is equidistant from the sides AB and AC.
So, ray BD will be the bisector of angle ABC.
