FAQs on Shortcuts to Solve Probability Question for CAT Video Lecture - General Aptitude for GATE - Mechanical Engineering

1. What are some common shortcuts to solve probability questions for CAT and banking exams?
Ans. Some common shortcuts to solve probability questions include using the formula for probability, understanding the concept of complementary events, using tree diagrams, and applying the concept of conditional probability.
2. How can I use the formula for probability to solve questions in CAT and banking exams?
Ans. The formula for probability is P(E) = (Number of favorable outcomes)/(Total number of possible outcomes). By using this formula, you can calculate the probability of an event occurring based on the given information.
3. What is the concept of complementary events in probability and how can it be used as a shortcut?
Ans. Complementary events refer to events that are the opposite of each other. For example, if event A is "getting a head when flipping a coin," then event A' (A complement) would be "getting a tail." By using the concept of complementary events, you can easily calculate the probability of an event not occurring by subtracting the probability of the event occurring from 1.
4. How can tree diagrams be used as a shortcut to solve probability questions in CAT and banking exams?
Ans. Tree diagrams are a visual representation of the possible outcomes of an event. By using tree diagrams, you can easily calculate the probability of a sequence of events occurring. Each branch of the tree represents a possible outcome, and the probability of each branch can be calculated by multiplying the probabilities along the branches.
5. How can the concept of conditional probability be applied as a shortcut to solve probability questions in CAT and banking exams?
Ans. Conditional probability refers to the probability of an event occurring given that another event has already occurred. It can be calculated using the formula P(A|B) = P(A and B)/P(B), where P(A and B) is the probability of both events A and B occurring, and P(B) is the probability of event B occurring. By using conditional probability, you can calculate the probability of an event based on the given conditions.
