Given a standard deck of 52 cards, assume you draw two cards from a standard deck of 52 cards and do not replace the first card before drawing the second card. Show how you solved the problems first with un-simplified fractions then convert to decimals rounding to 3 significant digits. a) P(1st card is a king and the 2nd card is a 5) b) P(both cards are fours) c) P(1st card has an even point value and 2nd card is a 7) d) P(neither card is a spade)
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.
