Class 11th Mathematics | Sets | Part 5

There are three mathematics teachers in a college in which there are 6 classes. In how many different ways can they choose the classes provided one teaches one class only

There are 11 teachers who teach Mathematics or Physics in a school, Of these, 7 teach Mathematics and 3 teach both Mathematics and Physics. How many teach Physics?

The probability that a student selected at random from class will pass in Mathematics is 4/5, and the probability that he/she passes in Mathematics and Computer Science is ½. What is the probability that he/she will pass in Computer Science if it is known that he/she has passed in Mathematics?

The probability that a student selected at random from class will pass in Mathematics is 4/5, and the probability that he/she passes in Mathematics and Computer Science is 1/2 . What is the probability that he/she will pass in Computer Science if it is known that he/she has passed in Mathematics?

The historgam below represents the scores obtained by 25 students in a Mathematics mental test. Use the data to : (iii) To determine the Modal class.

In class XI of a school 40% of the students study Mathematics and 30% study Biology. 10% of the class study both mathematics and biology. If a student is selected at random from the class, find the probability that he will be studying Mathematics or Biology or both.
