In a national park in Alaska, there are 100 polar bears. As a part of the monitoring of the park, the rangers caught 20 bears, tagged them and released them back into the park during the first year. A year later they caught 13 bears. (Assume the bears are caught at different times, and the same bear could be caught more than once.) A. What is the probability that 6 are tagged? B. What is the probability that none are tagged?
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.
