Os 234 entrevistados de uma pesquisa responderam à pergunta “Qual ou quais serviços de assinatura de vídeos sob demanda você possui?”. As únicas respostas foram sobre os serviços A, B ou C, sendo que cada entrevistado assina pelo menos um desses serviços. Do total de entrevistados, um terço assina o serviço A e 5 pessoas assinam os três serviços. O número de pessoas que assinam apenas o serviço B é o quádruplo do número de pessoas que assinam apenas os serviços B e C. Ninguém assina apenas os serviços A e B e 92 pessoas assinam o serviço C. São 31 pessoas que assinam apenas os serviços A e C.
O número de entrevistados que assinam apenas o serviço A excede o número de entrevistados que assinam apenas o serviço C em

José foi conhecer o novo restaurante de sua amiga Sueli. Ao chegar ao local, José viu que havia 3 restaurantes lado a lado, um de portas brancas, um de portas pretas e um de portas vermelhas e ele sabia que apenas um restaurante era o de Sueli e que cada atendente ou só mentia ou só dizia a verdade. José perguntou ao atendente de cada restaurante qual era o de Sueli, obtendo as seguintes respostas de cada atendente, identificado pela cor das portas do restaurante que trabalha:
(branca) O restaurante de portas brancas não é o de Sueli.
(preta) O restaurante de Sueli é o de portas vermelhas.
(vermelha) Eu sou o único atendente que fala a verdade.
Como José não foi capaz de identificar o restaurante com as respostas dadas, ele perguntou a cada atendente: “Você trabalha no restaurante de Sueli?”, e todos os atendentes responderam com “Não”.
A cor da porta do restaurante de Sueli e a cor da porta do restaurante que trabalha um atendente que disse a verdade são, respectivamente,

Advantages of wireless technology
Wireless communications offer several cost and connectivity benefits for organizations. The rapid rise of remote work – fuelled in part by the pandemic that began in 2020 – has created an environment where employees demand high-performance access to network resources regardless of where they might be.
Wireless networks can be less expensive to build and maintain since they require fewer switches and other components required by wired infrastructures. New wireless standards – especially among them multiuser, multiple input and multiple output – enable physical Access Points (APs) to serve a greater number of users, further reducing costs.
Wireless technologies also support novel services, among them location tracking, Internet of Things (IoT) deployments and remote diagnostics. Finally, advances in wireless performance enable organizations to stress mobility as a primary benefit, thus helping them redefine how they design their offices and workgroups.
