Question

Sue has a bag of 18 sweets.

5 of the sweets are blue
7 of the sweets are red
6 of the sweets are green
Sue takes at random a sweet from the bag.
Write down the probability that Sue
(i) takes a red sweet,
(ii) does not take a green sweet
(ii) takes a yellow sweet
​

Answer 1

(i) 38.9%

(ii) 33.3%

(iii) 0%

Explanation:

The total number of sweets is 18. The probability of picking a color can be determined by dividing the number of each color by the total:

Blue: 5/18 or 27.8%

Red: 7/17 or 38.9%

Green: 6/18 or 33.3%

Yellow: 0/18 or 00.0%

Totals 18/18 100%

Note that the question askes for Yellow sweets, but there are none.
