Answer:



I used the relative frequency method
Step-by-step explanation:
To solve this question we can use the relative frequency to find out each probability. The relative frequency is the ratio of the occurrence of each event and the total number of outcomes.
Here the experiment has been repeated 50 times, so that is the total number of outcomes and the denominator. There are 3 possible events E1, E2, and E3, so we can calculate the ratios to get the probabilities
Event E1 occurred 20 times of the 50:

Event E2 occurred 13 times of the 50:

Event E3 occurred 17 times of the 50:
