Answer:
[3x + (y/2)]
Step-by-step explanation:
English Translation
Suppose we have x confirmed cases of coronavirus and y suspected cases. A - If the confirmed cases triple and half of the suspects fall, we will have the following expression to represent the total number of cases:
Solution
Number of confirmed cases = x
Number of suspected cases = y
Number of confirmed cases triples and becomes 3x
Half of the suspected cases fall and becomes (y/2)
Total number of cases then becomes
[3x + (y/2)]
In Portugese/Em português
Número de casos confirmados = x
Número de casos suspeitos = y
O número de casos confirmados triplica e se torna 3x
Metade dos casos suspeitos cai e se torna (y / 2)
O número total de casos passa a ser
[3x + (y / 2)]

Determine the probability of winning at running and losing at swimming
First, we calculate the probability of losing at swimming using
Substitute 65% for P(Win)
![65\% + P(Lose[Swim]) = 1](https://tex.z-dn.net/?f=65%5C%25%20%2B%20P%28Lose%5BSwim%5D%29%20%3D%201)

![P(Lose[Swim]) = 1 - 65\%](https://tex.z-dn.net/?f=P%28Lose%5BSwim%5D%29%20%3D%201%20-%2065%5C%25)
![P(Lose[Swim]) = 35\%](https://tex.z-dn.net/?f=P%28Lose%5BSwim%5D%29%20%3D%2035%5C%25)
The required probability is then calculated using:
![Probability = P(Win[Run]) * P(Lose[Swim])](https://tex.z-dn.net/?f=Probability%20%3D%20P%28Win%5BRun%5D%29%20%2A%20P%28Lose%5BSwim%5D%29)
