Answer:
[tex]\frac{2}{5}[/tex] is the required probability.
Step-by-step explanation:
The probability P(A or B) when A and B are mutually exclusive events is P(A) + P(B)
Here A is the event hitting a Bull's eye
and B is the event throwing dart into 10 point ring.
The probability that he throws a dart into the center of the dart board (the Bull’s eye) = [tex]\frac{1}{10}[/tex].
The probability that he throws the dart into the 10-point ring = [tex]\frac{3}{10}[/tex]
Required probability = [tex]\frac{1}{10}[/tex]+ [tex]\frac{3}{10}[/tex] = [tex]\frac{4}{10}[/tex] = [tex]\frac{2}{5}[/tex]
