I don't get it why the answer was 0.3! isn't it 1/3?

Hey Mohamed,

Thank you for reaching out?

The first 3 answers are, in fact, the same. However, the question asks about the notation more than about the value itself. At minute 1:45, the lecturer states that "Even though we can express probabilities as percentages or fractions, conventionally, we write them out using real numbers between 0 and 1". That is the subtle reason why the answer to the quiz is 0.3(3) instead of 1/3.

Kind regards,
