I actually just learned this in 8th grade and it was so easy its crazy but its honestly simple it helps you solve the triangles and things and the equation is a squared + b squared = c squared and the a and b you would plug in the sides of the triangle or whatever shape your working with and square those numbers then find c by adding the two and then you square the c at the end and that will be your answer.

Responder:
70%
Explicación paso a paso:
probabilidad de seleccionar aleatoriamente a un participante que haya obtenido entre 71 y 85 puntos:
Probabilidad = resultado requerido / Total de resultados posibles
Resultados posibles totales = Sumando la frecuencia para obtener el número total de estudiantes = (9 + 12 + 12 + 18 + 9) = 60 estudiantes
Resultado requerido:
Clase :
(71 - 75) = frecuencia = 12
(76 - 80) = frecuencia = 12
(81 - 85) = frecuencia = 18
Total = (12 + 12 + 18) = 42 = resultado requerido
Por tanto, P = 42/60 = 0,7 = (0,7 * 100%) = 70%
