Question
The Pew Research Center asked a random sample of 2024 adult cell-phone 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.
Suppose we select one of the survey respondents at random.
Type of cell phone
Age
18-34 35-54 55+ Total
467
169 || 171 ||
171 127
214 189 100 503
Other 134 277 643 1054
Total
517 637 870 2024

Android
What is the probability that the person is not age 18 to
34 and does not own an iPhone?
189+100+277+643 = 0.776
503+1054
= 0.597
189+100+277+643
2024
214+134
2024
= 0.172
214+134 = 0.673
