A simple game of memory is played where a player is shown two cards for five seconds and then these cards are withdrawn. The player is asked if he has seen one or both of these cards in previous showings. If the user guesses correctly, his score is increased by one for each correct card. If he guesses wrong, then his score is decreased by one for each incorrect card. The pair of cards that are shown are denoted by CardA and CardB. Write the logical relationships involving propositions and propositional operators for the following situations: a) One of the cards was shown before and the user guessed it correctly. b) None of the cards were shown before and the user guessed incorrectly (which may include guessing incorrectly for a single card or for both cards) c) Both cards were shown before and the user guessed incorrectly (which may include guessing incorrectly for a single card or for both cards)
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.
