Question

fifty seeds were selected at random from each of 5 bags of seed and were kept under standardized conditions favorable to germination. after 20day the number of seed which had germination in each collection were counted and recorded as follow



after photo question ohk
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?​

Answer 1

Answer:

as more than 40 seeds contains only 3 bags (2,3and 5)

So we can write it as

3/5

a : answer 3/5

b: 0/5 as the highest seed on the bags were 48

c: answer is 5/5 as the least no. of seeds are 39 and the questions asked about 35 seeds . So the answer is 5/5 = 1

Answer 2

Answer:

ANSWER

(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
