The Pew Research Center asked a random sample of 2024 adult cellphone owners from the United States their age and which type of cell phone they own: iPhone, Android, or other (including non-smartphones). The two-way table summarizes the data.

Given:
The table contains data of 2024 adult cell-phone users.

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.
$\text{# of favorable outcomes}=1209$
The probability is the number of favorable outcomes divided by the number of possible outcomes:
$P\left(\text{Not 18 to 34 and not own iPhone}\right)=\frac{\text{# of favorable outcomes}}{\text{of possible outcomes}}$
$=\frac{1209}{2024}$
$\approx 0.5973$
$=59.73\mathrm{%}$
