The Pew Research Center polled a random sample of 2024 American adult cellphone owners to find out their age and if they own an iPhone, an Android, or something else (including non-smartphones). The data are summarized in the two-way table.

Let's say we choose one of the survey participants at random. What is the chance that the person is not between the ages of 18 and 34 and doesn't have an iPhone?

Given:
The table contains data of 2024 adult cell-phone users.
# of possible outcomes =2024
All people who arenot the age 18-34 and who do not own aniPhone are given in the rows "35-54" and "55+”, while they are also given in the columns Android” and "Other. Adding all corresponding counts, we then note that: this corresponds with 189+100+277+643=1209 individuals who are not age 18 to 34 and who do not own an iPhone.
# of favorable outcomes=1209
The probability is the number of favorable outcomes divided by the number of possible outcomes:
P(Not 18 to 34 and not own iPhone)=# of favorable outcomesof possible outcomes
=12092024
0.5973
=59.73%
