Question

Suppose a bag contains 30 white marbles, 10 purple marbles, and 8 green marbles.

One marble is randomly selected from the bag. In this situation, the probability of 1 could represent which event?

a. not selecting a yellow marble

b. selecting either a white or purple marble

c. selecting a green marble

d. selecting a white marble



Which BEST describes the probability of selecting a purple marble?

a. Likely

b. Certain

c. Impossible

d. Not likely

Answer 1

There’s a 48 percent chance of getting a purple marble so like not likely to get it and A is probably getting a white marble

Answer 2

Although you finished your assignment already, it’s still a significant part to understand this concept.

For our first question, the answer is A. This is because our bag does not contain any yellow marble, which means that it is impossible to get a yellow marble, which is why you would never pick a yellow marble from the bag. Hence why our answer is A.

For our second question, the answer is D. This is mainly because we have a total of 48 marbles and only 10 purple ones. This is a 10 out of 48 chance of getting a purple marble, which when converted into a percentage, we would get a 20.8% of getting a purple marble. Remember that this is our rule:

Impossible = 0%
Unlikely = Anything below 50% but above 0%
Equally Likely = Exactly 50%
Likely = Anything above 50% but below 100%
Certain = 100%

Using this rule, we know that 20.8% is unlikely, which is why it’s answer choice D.

I hope you have a nice day!! :)
