Question

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 5 number seds germinated 40 48. 42 39 41
​

Answer 1

(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
