Answer 1

Given: A randomly selected person chose 'Kayo' as their favorite streaming brand.

Required: To determine the probability that she is a female.

Explanation: Since there are two possibilities, i.e., a person can be a male or a female. Thus, n(S)=2.

Now, if E is the event that the person chosen is a female. The probability is-

$\begin{gathered} P(E)=\frac{n(E)}{n(S)} \\ =\frac{1}{2} \\ =0.5 \end{gathered}$

Final Answer: The probability that the person is female is 0.5
