Final answer:
In 1962, residents of Washington D.C. could not vote for president; this right was granted in 1964 with the Twenty-Third Amendment. African American women, including those in D.C., achieved full voting rights in every state after the Voting Rights Act of 1965.
Step-by-step explanation:
The question of whether Mary lives in Washington D.C. in 1962 and can vote for president centers on the history of voting rights in the United States. During that time, residents of Washington D.C. did not have the right to vote for the president of the United States. This was changed with the passage of the Twenty-Third Amendment in 1964, which granted residents of the District of Columbia the right to vote in presidential elections. Additionally, it's important to note that African American women, including those living in Washington D.C., gained the legal right to vote in every state only after the passing of the Voting Rights Act of 1965.
