Problem
A school keeps records of how regularly students complete their homework in four subjects. The probabilities that a randomly selected student has completed the homework on a given day are as follows:
Subject Probability
Mathematics 103
Science 28%
English 0.21
Social Studies x
Use the data above to answer the following:
(i) Convert the given probabilities for Mathematics, Science and English to decimal form.
(ii) Determine the value of x so that the probabilities for the four subjects together add up to 1.
(iii) Write the final list of probabilities for all four subjects in percentage form correct to one decimal place.
