¡Hola! Bienvenido a!
Vamos a sumar cuántas canicas tenemos en total.
12+11+17+5=45
Queremos hallar la probabilidad de elegir una canica que no sea azul. Observemos cuántas canicas no son azules.
12+11+5=28
Tendremos esta probabilidad sobre 48.
28/48
Al simplificar, obtenemos 7/12 o alrededor de 58.33%.
¡Espero que esto ayude!
