EPQP's answer to YH Tan's Primary 6 Maths Data Analysis Singapore question.
Thank you! But why did you multiply by 1/4?
1/1 - 1/5 gives you 4/ (1 x 5) which is not equal to 1 / (1 x 5) from the previous line.
For it to become 1/(1 x5) you need to divide by 4 or equivalently multiply by 1/4. The same logic applies to the rest of the numbers.

Ok I understand now thank you
