Question

On any given multiple choice question, there are 7 answers with 1 being correct. What's the probability of guessing the right one?

Answer 1

`1/7`

Explanation:

I am reading the question that we have a situation with a question, such as:

What is 1 + 1?

and we have 7 choices to pick from, say `1, 2, 3, 4, 5, 6, 7`

What is the probability of randomly picking the correct answer?

Remember that probability is a ratio (which can also be expressed as a decimal or percentage):

• the numerator is the number of ways we can satisfy a condition or conditions, and
• the denominator is the number of ways we can pick from the pool of choices

Out of the 7 choices someone can make (i.e. the denominator), only 1 is correct (i.e. the numerator). This gives us:

`P("randomly picking the right answer from 7 choices")=1/7`
