Uma urna contém quatro bolas vermelhas e dezesseis bolas azuis. Se três bolas forem sorteadas sucessivamente com reposição, ou seja, se cada bola sorteada é devolvida à urna antes de se sortear a próxima, então a probabilidade de que ao menos uma bola vermelha seja sorteada é igual a:

Você está diante de duas urnas que contêm muitas bolas. A urna I só tem bolas vermelhas, a II só tem bolas azuis. Ambas têm, nesse momento, a mesma quantidade de bolas. Você pega uma quantidade grande de bolas vermelhas e as passa para a urna II. Em seguida você mistura bem as bolas da urna II e dela retira, aleatoriamente, a mesma quantidade de bolas que você tinha passado da urna I para a urna II. Assim, as duas urnas voltam a ter a mesma quantidade de bolas. Se compararmos a quantidade x de bolas azuis que agora estão na urna I com a quantidade y de bolas vermelhas que agora estão na urna II, avalie se as seguintes afirmativas são falsas (F) ou verdadeiras (V):
As afirmativas são respectivamente:

Um campeonato de futebol foi disputado por 16 equipes em sistema de turno e returno, ou seja, cada equipe jogou duas vezes com cada uma das demais. Como sabemos, em cada jogo o vencedor faz 3 pontos e o perdedor não faz ponto algum; em caso de empate, cada equipe faz um ponto. Terminado o torneio, constatou-se que as equipes somaram um total de 635 pontos. Assim, se dividirmos o número de jogos do campeonato que terminaram empatados pelo número de jogos em que houve vencedor obtemos aproximadamente:

Assim, ao reunir as três convicções, o delegado conclui acertadamente que:
Um campeonato mundial de certo jogo eletrônico será disputado on-line por 25.821 competidores de todo o mundo. Cada partida é disputada por dois jogadores. O vencedor segue no torneio, o perdedor é eliminado. Assim, esse campeonato terá a seguinte quantidade de jogos:
TEXT II
Like Castles In An Aquarium, Offshore Drilling Platforms Are Sprawling With Residents
Just beneath the ocean’s surface, there’s an unseen world that most people will never have the opportunity to witness firsthand. A place where nature and mankind have struck a balance – a mutual respect, a friendship of sorts.
Offshore drilling platforms have become home to vast communities of sea life. Florid carpets of coral encrust their massive pylons, along with sponge, sea urchins, crabs, and snails. Swimming in the sanctuary of their enormous risers are schools of rockfish, bright orange garibaldi and angel fish. And splashing about on the surface is the occasional sea lion.
Now scientists have confirmed what some had suspected all along. Most of the sea life was actually created at the rig rather than having come from other parts of the ocean and settled there, according to the National Academy of Sciences. And fish that would otherwise perish in vast expanses of open ocean, settle within the safety of the structures.
Like castles in an aquarium, offshore platforms are sprawling with underwater residents. Scientists say these are the richest marine ecosystems on the entire planet. They are even more productive than coral reefs and estuaries, according to marine biologists.
The first thing anyone – trained scientist or casual recreational diver – notices around a rig is the big fish -- lots of them, say marine researchers and divers, alike.
For a decade and a half, researchers used submersibles to survey fish at 16 different platforms. When the researchers tabulated the data, they were surprised to discover that, by one standard, California’s oil rigs are among the most productive marine habitats ever recorded.
At the end of their production, however, the offshore rigs must be decommissioned. Scientific insight is adding momentum to efforts to convert some of these rigs into artificial reefs […].
