If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up. An organisation selected families at random and surveyed them to determine a relationship between income level and the number of vehicles in a family.

The information gathered is listed in the byjis. Suppose a family is chosen. A teacher wanted to analyse **byjus class 1 maths 30** performance of two sections of students in a mathematics test of marks. Looking at their performances, she found that a few students got under 20 marks and a few got 70 marks or clqss. So she decided to **byjus class 1 maths 30** them into intervals of varying sizes as follows 0 � **byjus class 1 maths 30,** 20 � 30, �, 60 kaths 70, 70 � To know the opinion of the students about the subject statistics, a survey of students was conducted.

The data is recorded in the following table Find the probability that a student chosen at random i likes statistics, ii does not like it. The distance in km of 40 engineers from their residence to their place of work were found as follows What is the empirical probability that an engineer lives i less than 7 km from her place of work?

Activity: Note the frequency of two-wheelers, three-wheelers and four-wheelers going past during a time interval, in front of your school gate. Find the probability that any one vehicle out of the total vehicles you have observed is a two-wheeler? Solution: It is an activity. Students can do it themselves. Activity : Ask all the students in your class to write a 3-digit number.

Choose any student from the room at random. Remember that a number is divisible by 3, if the sum of its digit is divisible by 3. Solution: A class room activity for students.

Eleven bags of wheat flour, each **byjus class 1 maths 30** 5 kg, actually contained the following weights of flour in kg 4. A study was conducted to find out the concentration of sulphur dioxide in the air in parts per million ppm of a certain city.

The data obtained for 30 days is as follows You were asked to prepare a frequency distribution table, regarding the concentration of sulphur dioxide in the air in parts per million of a certain city for 30 days.

Using this table, kaths the probability of the concentration of sulphur dioxide in the interval 0. Use this table to determine the probability that a student of this class, selected at random, has blood group AB. RD Sharma Class 12 Solutions.
