Question

Eleanor placed some marbles in a bag for an experiment. She reaches into the bag and grabs a marble. Eleanor writes down the color of the marble then places the marble back into the bag. This process is repeated 100 times. The marbles are either red, black, or gray. The probabilities of randomly choosing a marble of a given color are shown below.

P(black) = 0.65
P(red) = 0.11
P(gray) = 0.24
Which of the following best describes the probability that the next randomly chosen marble is black?

A.
unlikely

B.
somewhat likely

C.
certain

D.
very likely

Answer 1

The probability of randomly choosing a black marble is given as \( P(black) = 0.65 \).

A probability of 0.65 indicates that there is a 65% chance of picking a black marble on any given trial. This is a high probability, suggesting that it is more likely than not that the marble chosen will be black.

Given the options provided:

- A. unlikely
- B. somewhat likely
- C. certain
- D. very likely

The best choice to describe the probability that the next randomly chosen marble is black is:

**D. very likely**
