# What is the probability that a marble is drawn at random from a bag?

## What is the another possible number of marbles in the bag?

(i) The least possible number of marbles in the bag is 31, since 30 is the amount of marbles each person can have evenly, +1 makes 1 leftover. So for the first answer, it is A. Another possible number of marbles in the bag is 61 since 60 is divisible by 2, 3, and 5, +1 makes 1 leftover.

What is the probability that a marble pulled out of the bag at random will be either red or green?

The probability that the marble is either red or green is 0.8. The probability that the marble is neither red nor green is 0.2.

What is the probability of getting a red marble?

The probability of drawing a blue marble is now = 1/4. The probability of drawing a red marble = 2/5.

### Would it be likely to pull a blue marble than a green marble from the bag?

You are equally likely to draw a blue marble or a green marble. You are equally likely to draw any of the colors from the bag. You are equally likely to draw a red or a black marble. You are less likely to draw a black marble than a blue marble.

### What is the probability of picking white marbles?

What is the probability of obtaining a red marble?

The probability of drawing a red marble = 2/5.

What is the likelihood of pulling out red marble?

Note that there are 16 total marbles. A is simply a set of sequential events. On the first, you have 10/16 chances to draw a red. Supposing this red is not replaced, the chance of drawing a second red will be 9/15; therefore, the probability of A is (10/16) * (9/15) = 0.375.

#### How many marbles are there in the bag of marbles?

Similarly, if (a) occurred, the probability of (b) is 4 9, since there are now only nine marbles in the bag, of which four are non-red. The combined probability of (a) and (b) occurring is therefore

#### How many ways to select two white marbles?

How many ways to select two white marbles? Multiply them together and you have the number of ways to select two black and two white. The other is in line with your comment. There are ( 4 2) = 6 ways to order the two black and two white, and you already calculated the probability of pulling specifically white, white, black, black.

What is the probability of 5 non-red marbles?

The probability of (a) is 5 10 = 1 2, since there are 2 + 3 = 5 non-red marbles. Similarly, if (a) occurred, the probability of (b) is 4 9, since there are now only nine marbles in the bag, of which four are non-red.
