QUESTION 8 Researchers are studying whether eating more than 1500 calories a day is related to obesity. The notation for the events being studied is: N for Normal weight, S for Somewhat obese, O for Obese; M for More than 1500 calories a day: MC for Not More than 1500 calories. What is the probability that a randomly selected person from those who eat More than 1500 calories a day is Somewhat obese or Obese? Normal (N) Somewhat (S) 30 | Obese (0) Total More than 1500 (M) 60 20 110 20 10 40 70 Not More(M) so 160 P(S U ON M) = Total 40 60 180 180 50 P(S U O| M) = 110 100 P(S U O) 180 50 P(M | SUO) = 100
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

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.
