There are 7 acts in a talent show. An acrobat, a comedian, a guitarist, a pianist, a singer, a violinist, and a whistler. A talent show host randomly schedules the 7 acts. Compute the probability of each of the following events. Event A : The whistler is first, the pianist is second, the acrobat is third, and the guitarist is fourth. Event B: The first four acts are the comedian, the pianist, the guitarist, and the acrobat, in any order. \( P(A)=\square \) \( P(B)=\square \)

In an aquarium, there are 7 large fish and 6 small fish. Half of the small fish are red. One fish is selected at random. Find the probability that it is a small, red fish. Write your answer as a fraction in simplest form.

03- Um restaurante está com 13 pessoas: 9 clilentes e 4 garçons. Se escolhermos urna pessoa do local aleatoriamente, qual a probabilidade de ser um cliente? a) \( 3 / 13 \) ad \( 9 / 13 \) c) \( 6 / 13 \) d) \( 7 / 13 \)

\( \begin{array}{l}\text { Place the question numbers on } \\ \text { the probability scale below, } \\ \text { where you think they go. } \\ 8 \\ \text { The rolling of a number less } \\ \text { than } 3 \text { with a fair die. } \\ 9 \text { Selecting a red card from a } \\ \text { deck of cards } \\ 10 \text { The chance of buying one } \\ \text { ticket and winning the lottery. } \\ 11 \text { Selecting a number card }\end{array} \).
