Question

John is playing a gamr of darts. The probability that he throws a dart into the center of the dart board (bulls eyes) is 1/10. The probability tgat he throws rhe dart the dart into the dart into the 10 point ring is 3/10. What is the probability that he either hits a bullseye or scores 10 points?

Answer 1

Answer:

2/5

Step-by-step explanation:

Answer 2

Answer:

$\bf\textbf{The probability that he either hits a bulls eye or scores 10 points = }\frac{2}{5}$

Step-by-step explanation:

$\text{The probability that he throws a dart into the center of the dart board = }\frac{1}{10}$

$\text{The probability that he throws the dart into the 10 point ring = }\frac{3}{10}$

Now we need to find the probability that he either hits a bulls eye or scores 10 points.

The probability that he either hits a bulls eye or scores 10 points = Probability that he hits the bulls eye + Probability that he throws the dart into the 10 point ring

$\text{The probability that he either hits a bulls eye or scores 10 points = }\frac{1}{10}+\frac{3}{10}$

$\text{The probability that he either hits a bulls eye or scores 10 points = }\frac{4}{10}$

$\bf\textbf{The probability that he either hits a bulls eye or scores 10 points = }\frac{2}{5}$
