#FUVEST Hello, welcome to my channel. Come see question 24 of FUVEST 2018, about probability. In an urn, there are yellow, white, and red balls. We know that: I. The probability of drawing a red ball from this urn is twice the probability of drawing a yellow ball. II. If 4 yellow balls are drawn from this urn, the probability of drawing a red ball becomes 1/2. III. If 12 red balls are drawn from this urn, the probability of drawing a white ball becomes 1/2: Discover Professor Mateca's platform at: https://www.professormateca.com.br/ -------------------------------------------------------------------------------------------------------------------------------------- Pre-Calculus Course (Functions) If you want to learn EVERYTHING about functions at the basic education level, come take a complete course with me.
