**Probability class 7 formulas**

**Probability of an event:**Probability is a number between 0 and 1, which represents the likelihood of an event occurring. The formula for probability is:

Probability (P) = Number of favorable outcomes / Total number of possible outcomes

**Complementary Probability:**The complementary probability of an event is the probability that the event will not occur. The formula for complementary probability is:

Complementary Probability = 1 – Probability of an event

**Addition Rule of Probability**: The addition rule of probability is used when two or more events are mutually exclusive, i.e., they cannot occur at the same time. The formula for the addition rule of probability is:

P (A or B) = P (A) + P (B)

**Multiplication Rule of Probability:**The multiplication rule of probability is used when two or more events are independent, i.e., the occurrence of one event does not affect the occurrence of another event. The formula for the multiplication rule of probability is:

P (A and B) = P (A) × P (B)

**Conditional Probability**: Conditional probability is the probability of an event occurring given that another event has already occurred. The formula for conditional probability is:

P (A|B) = P (A and B) / P (B)

Where, P(A|B) is the conditional probability of event A given that event B has occurred, P(A and B) is the probability of both events A and B occurring, and P(B) is the probability of event B occurring.

**FAQs**

**Q: What is probability in Class 7 maths?**

A: Probability is a branch of mathematics that deals with the study of random events or outcomes. It is the measure of the likelihood of an event occurring. In Class 7 maths, students learn the basic concepts of probability, including the formula of probability, mutually exclusive and independent events, and conditional probability.

**Q: What are the basic concepts of probability in Class 7 maths?**

A: The basic concepts of probability in Class 7 maths include the formula of probability, mutually exclusive and independent events, and conditional probability. Students also learn about the different ways of representing probabilities, such as fractions, decimals, and percentages.

**Q: How do I find the probability of an event in Class 7 maths?**

A: To find the probability of an event in Class 7 maths, you need to use the formula of probability:

Probability (P) = Number of favorable outcomes / Total number of possible outcomes

You can also represent probabilities in fractions, decimals, and percentages.

**Q: What is the difference between mutually exclusive and independent events in probability?**

A: Mutually exclusive events are events that cannot occur at the same time. For example, if you toss a coin, you cannot get both heads and tails at the same time. Independent events are events where the occurrence of one event does not affect the occurrence of another event. For example, if you toss a coin twice, the outcome of the first toss does not affect the outcome of the second toss.

**Q: How do I solve probability problems in Class 7 maths?**

A: To solve probability problems in Class 7 maths, you need to understand the basic concepts and formulas of probability. You should also practice solving Probability Class 7 Worksheets and extra questions. It is important to read the problem carefully and identify the given information, such as the number of favorable outcomes and the total number of possible outcomes. You can then use the formula of probability to find the probability of the event.

**Q: How can I improve my probability skills in Class 7 maths?**

A: To improve your probability skills in Class 7 maths, you should practice solving Probability Class 7 Worksheets and extra questions. You should also review the basic concepts and formulas of probability and try to understand their applications. You can also use online resources, such as videos and tutorials, to supplement your learning.
