Question

21. 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 in each collection were counted and recorded as follows:
Bag
1
2
3
4
No:of seeds 40
48
42
39
germinated
5
41
What is he probability of germination of
(i) more than 40 seeds in a bag ?
(ii) 49 seeds in a bag ?
(iii) more than 35 seeds in a bag ?


Please help me ​

Answer 1

Answer:

50 seeds were selected at random from 5 bags

Answer 2

(i) 0.60

(ii) 0

(iii) 1

Step-by-step explanation:

(i) Number of bags in which more than 40 seeds out of 50 seeds germinated =3

So, P (more than 40 seeds in a bag germinated) =

5

3

=0.60

(ii)Number of bags in which 49 seeds germinated =0

So, P (49 seeds germinated in bag) =

5

0

=0

(iii) Number of bags in which more than 35 seeds out 50 seeds germinated =5

Total number of bags=5

So, P(more than 35 seeds in a bag germinated) =

5

5

=1
