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.
