NIVEL: AVANZADO 7) Norma y Eduardo juegan a extraer, al azar, cartas de una baraja de 52 cartas. Determinar su espacio muestra ( \( \Omega \) ), y el suceso A : "Obtener una carta mayor que 9 ? Explain why choosing two socks from a drawer containing blue, red, and green socks is an example of dependent events. Qual é a probabilidade de um número primo ser sorteado entre 0 e 100 ? Responda em fração, decimal e porcentagem. Un equipo de investigación de mercado realiza un estudio controlado para determinar cuáles marcas de celular prefieren las personas. La muestra con- siste de 200 personas, y a cada una se le pide probar dos marcas (Samsung y iPhone) durante un periodo de varios meses. Con base en las respuestas de la encuesta, el equipo de investigación compila las siguientes estadísticas acerca de las preferencias de celulares. - De quienes usan Samsung en cualquier mes, \( 70 \% \) siguen usándolo el mes siguiente, mientras que cl \( 30 \% \) cambia a iPhone. - De quienes usan iPhone en cualquier mes, \( 80 \% \) siguen usándolo el mes siguiente, mientras que el \( 20 \% \) cambian a Samsung. Suponga que cuando inicia el estudio 120 personas usan Samsung y 80 perso- nas usan iPhone. ¿Cuántas personas usarán cada marca 1 mes después? ¿Y 2 meses después? ¿Y un año después? Si lanzas un dado y luego una moneda, ¿son estos eventos independientes? Explica por qué. (d) Find and interpret the probability that a randomly selected fertilized egg hatches between 17 and 21 days.

Select the correct choice below and fill in the answer box to complete your choice. (Round to the nearest integer as needed.) A. If 100 fertilized eggs were randomly selected, \( \square \) of them would be expected to take more than 23 days to hatch. B. If 100 fertilized eggs were randomly selected, exactly \( \square \) would be expected to hatch on day 23 . C. In every group of 100 fertilized eggs, \( \square \) eggs would be expected to hatch in more than 23 days. The probability that a randomly selected fertilized egg takes over 23 days to hatch is (Round to four decimal places as needed.)
