Question

Hundred seeds were selected at random from each of 4 bags of seeds, and were kept under
standardized 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
Number of seeds germinated -90 92 64 81
What is the probability of germination of [3]
(i) less than 90 seeds in a bag?
(ii) 90 seeds in a bag?
(iii) more than 95 seeds in a bag?
(iv) Number is perfect square
(v) Also give example that having probability 1
(vi) Also give example that having probability 0

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
