A bag contains 9 RED beads, 8 BLUE beads, and 3 GREEN beads. If a single bead is picked at random, what is the probability that the bead is RED or GREEN

Respuesta :

Answer:

0.6 = 60% probability that the bead is RED or GREEN.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question, we have that:

There are 9 + 8 + 3 = 20 beads.

Of those, 9 + 3 = 12 are red or green.

So, there is a [tex]\frac{12}{20} = 0.6[/tex] probability that the bead is RED or GREEN.
