In general language at the most means that the set can have value less than or equal to that value. For example in a bag of balls numbered 1 to 20, the ball having number at the most 10 means a group of balls having value less than or equal to 10. At most in the probability means that the favorable cases are those possibilities that that are smaller than or equal to that value. So, we can say that at most means maximum value the group can have.
Illustration: Fifty seeds were selected at random from each of 5 bags of seeds, and were kept under standarised conditions favorable to germination. After 20 days the number of seeds which had germinated in each collection were counted and recorded as follows:
Bag: | 1 | 2 | 3 | 4 | 5 |
Number of seeds germinated: | 40 | 48 | 42 | 39 | 41 |
What is the probability of germination of:
(i) more than 40 seeds is a bag?
Solution:Total number of bags = 5
Bags in which more than 40 seeds germinated out of 50 seeds are 2, 3, and 5
So total number of bags in which more than 40 seeds germinated out of 50 seeds = 3
Probability of germination of more than 40 seeds in a bag
(ii) at most 40 seeds in a bag?
Solution:Total number of bags = 5
Bags in which at most 40 seeds germinated out of 50 seeds are 1 and 4
So total number of bags in which at most 40 seeds germinated out of 50 seeds = 2
Probability of germination of at most 40 seeds in a bag
Fifty seeds were selected at random from each of 5 bags of seeds, and were kept under standardised conditions favourable to germination. After 20 days, the number of seeds, which had germinated was counted and recorded as follows :

It was a good experience with Abhyas Academy. I even faced problems in starting but slowly and steadily overcomed. Especially reasoning classes helped me a lot.
My experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
It has a great methodology. Students here can get analysis to their test quickly.We can learn easily through PPTs and the testing methods are good. We know that where we have to practice
My experience with Abhyas academy is very good. I did not think that my every subject coming here will be so strong. The main thing is that the online tests had made me learn here more things.
Abhyas is a complete education Institute. Here extreme care is taken by teacher with the help of regular exam. Extra classes also conducted by the institute, if the student is weak.
About Abhyas metholodology the teachers are very nice and hardworking toward students.The Centre Head Mrs Anu Sethi is also a brilliant teacher.Abhyas has taught me how to overcome problems and has always taken my doubts and suppoeted me.
I have spent a wonderful time in Abhyas academy. It has made my reasoning more apt, English more stronger and Maths an interesting subject for me. It has given me a habbit of self studying
One of the best institutes to develope a child interest in studies.Provides SST and English knowledge also unlike other institutes. Teachers are co operative and friendly online tests andPPT develope practical knowledge also.
Being a parent, I saw my daughter improvement in her studies by seeing a good result in all day to day compititive exam TMO, NSO, IEO etc and as well as studies. I have got a fruitful result from my daughter.
A marvelous experience with Abhyas. I am glad to share that my ward has achieved more than enough at the Ambala ABHYAS centre. Years have passed on and more and more he has gained. May the centre flourish and develop day by day by the grace of God.
