Question

13. Two dice are thrown simultaneously. Find the probability of obtaining a total score 5.
OR
A die is thrown once What is the probability of getting a number greater than 4
14. Find the class mark of classes 10-25 and 35-55.
OR
Find the value of r, if the mode of the following data is 25
15.20.25. 18. 14.15, 25, 13. 18.10.20.25.20...18
15. Find the valuc of p if the lines represented by the equations 3x-y-5=0 and
6x-2y-p = 0 are parallel​

Answer 1

Answer:

13. 4/36= 1/9

OR

2/6= 1/3

14. Class mark of 10-25

(10+25)/2=

= 35/2

= 17.5

Class mark of 35-55

(35+55)/2

= 45

OR

The frequency table of the given data is as given below:

Value (xi ): 14 15 16 18 20 25 x

Frequency (f i ): 1 3 1 3 3 3 1

It is given that the mode of the given data is 25. So, it must have the maximum frequency. That is possible only when x=25.

Hence. x=25.
