Question

50 seeds were selected at random from each of 5 bags of seeds and were kept under standarddised 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

No of seed s germinated 40 48 42 39 41

What is the probability of germination of:

(a) More than 40 seeds in a bag

(b) 49 seeds in a bag

(c) More than 35 seeds in a bag

(d) At least 40 seeds in a bag

(e) Atmost 40 seeds in a bag​

Answer 1

Answer:

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
