Questiona ball is drawn randomly from a jar that contains 13 ed balls, 16 green balls, and 9 blue balls, find the probability of the following events.
You may answer using a fraction or decimal rounded to three places. (a) A red ball is drawn: $\square$ (b) A green ball is drawn: $\square$ (c) A blue ball is drawn: $\square$ (d) A black ball is drawn: $\square$ (e) A red or green ball is drawn: $\square$

Studdy Solution
Calculate the probability of drawing a red or green ball:
$$\frac{13 + 16}{38} = \frac{29}{38}$$
The probabilities are: (a) A red ball is drawn: $\frac{13}{38} \approx 0.342$ (b) A green ball is drawn: $\frac{16}{38} \approx 0.421$ (c) A blue ball is drawn: $\frac{9}{38} \approx 0.237$ (d) A black ball is drawn: $0$ (e) A red or green ball is drawn: $\frac{29}{38} \approx 0.763$
