Question

What is the probability of drawing a red marble?

Answer 1

`\sf \: (1)/(4)`

Explanation:

since the total of red marbles is 5 and the total of all the colours of marble is 20

therefore we write it like this;

`\sf (Total \: of \: red \: marbles)/(Total \: of \: all \: the \: marbles)`

`\rightarrow \sf \: (5)/(20) = (1)/(4)`

Answer 2

The total number of marbles is 20.
There are 5 red marbles.

The probability of drawing a red one is 5/20. You can simplify to 1/4
