Answer
Answer: (b) Probability
Explanation: Probability deals with finding out the likelihood of the occurrence of an event.
Combination is a technique to determine the number of possible arrangements in a collection of items where the order of selection doesn’t matter.

25. Complete the table: (Numbers are not repeated)
| Event: Sum of 2 natural numbers till 10 |
5 |
10 |
13 |
| Probability | ….……a……. | ….……..b………… | ….……..c………. |
(a) a= 3/10, b = 3/10, c = 1/10
(b) a= 1/10, b = 3/10, c = 1/5
(c) a= 3/10, b = 2/5, c = 2/5
(d) a= 2/5, b = 3/10, c = 1/10
Answer
Answer: (c) a= 3/10, b = 2/5, c = 2/5
Explanation:
for a,
Total no. Of events = {1……….10}= 10
No. Of favourable events = Sum is 5 = {(1,4), (2,3), (3,2)} = 3
Probability = 3 /10
For b,
Total no. Of events = {1……….10} = 10
No. Of favourable events = Sum is 10 = {(1,9), (2,8), (3,7), (4,6)} = 4
Probability = 4 /10 = 2/5
For c,
Total no. Of events = {1……….10} = 13
No. Of favourable events = Sum is 13 = {(3,10), (4,9), (5,8), (6,7)} = 4
Probability = 4 /10 = 2/5
