Example 10 : 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:

What is the probability of germination of
more than 40 seeds in a bag?
(ii) 49 seeds in a bag?
(iii) more that 35 seeds in a bag?​

Answer 1

Answer:

1) 4/5

2) 0/5 = 0

3) 5/5 = 1

Step-by-step explanation:

Probability = Number of observations

----------------------------------------

Total number of Outcomes

Data ,

Bags with seeds that germinated more than 40 seeds - 4 bags

Bags with seeds that germinated 49 seeds - 0 bags

Bags with seeds that germinated more than 35 seeds - 5 bags

1) P(getting a germination of more than

40 seeds in a bags) = 4/5

2) P(getting a germination of 49 seeds

in a bag) = 0/5 = 0

3) P(getting a germination of more than

35 seeds in a bag) = 5/5 = 1
