A coin- operated machine sells plastic rings. It contains 6 yellow rings, 11 blue rings, and 3 black rings. Sara puts a coin in the machine. Find the theoretical probability she gets a black ring. Express your answer as a decimal. If necessary, round your answer to the nearest tenth

P(black) = 0.2

Step-by-step explanation:

Total number of rings

= 6 yellow + 11 blue + 3 black

= 20 rings.

P(black) = #black/#all = 3/20 = 0.15

Most people would round 0.15 to the nearest tenth as 0.2

It is not desirable in this cas to round to the tenth due to the 33% round-off error, but, what can you do.
