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%
