To know the opinion of the students about Mathematics, a survey of 200 students was conducted. The data is recorded in the following table: Opinion: Like Dislike No. of students 135 65 Find the probability that a student chosen at random (i) like Mathematics  (ii) does not like it.

To know the opinion of the students about Mathematics, a survey of 200 students was conducted. The data is recorded in the following table: Find the probability that a student chosen at random (i) likes Mathematics (ii) does not like it.

A survey of 300 girls of a school was conducted and it was found that 108 girls like tea and 192 dislike it. Out of these girls one girl is selected at random. What is the probability that the selected girl (i) likes tea (ii) does not like tea.

In a particular section of class IX, 40 students were asked about the month of their birth and the following graph was prepared for the data so obtained. Find the probability that a student of the class was born in August.

The scores in mathematics test (out of 25) of 15 students are as follows: Find the mode and median of this data. Are they same?

In a school, 300 students were surveyed. The survey showed that 186 students liked watching cricket match while the rest disliked it. Out of these students, if one student is chosen at random, what is the probability that the chosen student : (i) likes watching cricket match? (ii) dislikes watching cricket match?

The marks distribution of 30 students m a mathematics examination are given in Table of Example 1. Find the mode of this data.

A survey shows that 69% students like mathematics, whereas 75% like chemistry. If x% students like both the subjects, then the maximum value of x is

In a school 25% students are failed in Mathematics, 15% in Physics and 5% students fail in both Mathematics and Physics. A student is selected at random. (i) If he is fail in Physics, find the probability that he is fail in Mathematics. (ii) If he is fail in Mathematics, find the probability that he in fail in Physics. (iii) Find the probability that he is fail either in Mathematics or in Physics.

A Mathematics aptitude test of 50 students was recorded as follows: Draw a histogram for the above data using a graph paper and locate the mode:

In a class of 125 students 70 passed in Mathematics, 55 in statistics, and 30 in both. Then find the probability that a student selected at random from the class has passes in only one subject.
