After solving, the probability that we select a gold marble is 2/31.
In the given question,
A bag contains 2 gold marbles, 8 silver marbles, and 21 black marbles.
So, Total marbles = 2+8+21
Total marbles = 31
As we know that, probability refers to the likelihood that an event will occur. If we don't know how such an event will end out, we can analyze the probability or likelihood of various outcomes. Statistic is the analysis of events that follow a probability distribution.
We have to randomly select one marble from the bag then we have to find the probability that we select a gold marble is
P(G) = Total number of gold marble/Total marbles
P(G) = 2/31
Hence, the probability that we select a gold marble is 2/31.
