Without further information, it is impossible to determine the probability of selecting a purple marble.
Suppose a bag contains 30 white marbles, 10 purple marbles, and 8 green marbles. Which BEST describes the probability of selecting a purple marble?
Responses
A Certain
B Not likely
C Likely
D Impossible
B Not likely (but possible) - There are 10 purple marbles out of a total of 48 marbles. Therefore, the probability of selecting a purple marble is only 10/48, which is less than a 1 in 4 chance.
To determine the probability of selecting a purple marble, we would need to know the total number of marbles and the number of purple marbles. Without this information, we cannot accurately determine the probability. Therefore, none of the given options (A, B, C, D) can be the correct answer because they all make assumptions about the probability without providing the necessary information.
