Question

There is a bag of colored beads in the craft box. The colors of the 50 beads are shown in the table below.

Answer 1

We know there is a total of 50 beads. Since a bead can't be two colors at the same time

`P(A\cup B)=P(A)+P(B)`

In this case

`P(R\cup G)=P(R)+P(G)=(7)/(50)+(8)/(50)=(15)/(50)=0.3`

Thus, the probability of selecting a red or green bead is 0.3 or 30%
