Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance
Imagine you and 3 of your friends are planning to go to the playground at 6 in the evening. Your house is one mile away from the playground and one of your friends named Jim must start at 5 pm to reach the playground by walk. The other two friends are 3 miles away.
Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.

Part B: One student will be selected at random from the class. Consider events X and Y shown.
X: the selected student is female
Y: the selected student is right-handed
Which of the following statements about events X and Y is TRUE?
O A. The events are independent because the number of right-handed students in the class is larger than the number of female
students.
O B. The events are independent because the number of categories for dominant hand is different from the number of categories for
gender.
C. The events are not independent because for one of the dominant hand categories the number of female students is 0.
O D. The events are not independent because the probability of X is not equal to the probability of X given Y.
