Question

There are 4 red marbles, 5 green marbles, 6 yellow marbles and 3 blue marbles in a bag. You select one marble at random. What is the probability that it will be yellow?

Answer 1

Answer:

The probability can be written as;

6/18

0.333

33.3%

Step-by-step explanation:

First we find the total number of marbles.

4 + 5 + 6 + 3 = 18

Now write the probability in the form of (favourable outcomes / possible outcomes), or 6/18.

Now let's divide.

6 ÷ 18 = 0.33333333... repeating decimal

0.333 × 100 = 33.33333.....%

We can also round this to 33%
