Question

suppose a bag contains 12 green cubes, 5 blue cubes, and 3 yellow cubes. find each probability if you choose one cube at random. what is the probability of not choosing a blue cube? 2/5 3/5 1/4 3/4

Explanation:

Step1: Calcular total de cubos

Sumar los cubos de cada color: \( 12 + 5 + 3 = 20 \) cubos en total.

Step2: Calcular cubos no azules

Cubos no azules son verdes + amarillos: \( 12 + 3 = 15 \) cubos.

Step3: Calcular probabilidad

La probabilidad de no elegir azul es \( \frac{\text{cubos no azules}}{\text{total de cubos}} = \frac{15}{20} = \frac{3}{4} \).

Answer:

3/4
