, SECTION A: PROBABILITY
1.1 Drawing Marbles from a Bag (Total Marbles = 10)
A bag contains 10 marbles of different colours:
Red: 3
Blue: 4
Green: 2
Yellow: 1
1.1.1 Theoretical Probability
Theoretical probability is calculated based on the known ratio of each colour in the total
number of marbles. The formula used is:
So, for each colour:
Red: 3/10 = 0.3
Blue: 4/10 = 0.4
Green: 2/10 = 0.2
Yellow: 1/10 = 0.1
These probabilities represent the expected likelihood of drawing each colour marble
from the bag if each draw is random and equally likely.
1.1.2 Experimental Results from 14 Trials
In a real-life activity, marbles were drawn 14 times with the following results:
