Question

11. Find the median of the data: 3, 11, 7, 2,5,9, 9, 2, 10, 15,7
12. The probability of getting a number greater than 2 on throwing a die once is
13. The mode of the observations 23, 26, 15, 12, 28, 38, 19, 23, 26, 23 is 28.
14. Find the median of the data : 21, 15, 6, 25, 18, 13, 20, 9, 8, 12​

Answer 1

11.2<3<5<7<9<10<11<15

median = 7+9

=16/2

=8

12. no. of favourable outcomes = 4

total no. of possible outcomes =6

probability = no. of favourable outcomes /total no. of possible outcomes

probability = 4/6

=2/3

13. 23 is the mode

14.6<8<9<12<13<15<18<20<21<25

median = 13 + 15

= 28/2

= 14
