Se hace una encuesta en un grupo de 120 personas, preguntando si les gusta leer y ver la televisión. Los resultados son: - A 32 personas les gusta leer y ver la tele. - A 92 personas les gusta leer. - A 47 personas les gusta ver la tele. Si elegimos al azar una de esas personas: a) ¿Cuál es la probabilidad de que no le guste ver la tele? b) ¿Cuál es la probabilidad de que le guste leer, sabiendo que le gusta ver la tele? C) ¿Cuál es la probabilidad de que le guste leer?

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

the first option is the answer.

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years
