Culture anglophone : pays et langues officielles

We are studying three English-speaking countries: the United Kingdom, Australia, and Canada. Let $n$ be the number of countries. We know that the United Kingdom's capital is London, Australia's capital is Canberra, and Canada's capital is Ottawa. If each country has exactly $1$ official language commonly recognized in this context (English), calculate the total number of official languages $T$ using the formula $T = n \times 1$. What is the value of $n$ and $T$?
