Question

PLZZ answer it's urgent​

Answer 1

Answer- The above question is from the chapter 'Probability'.

Concept used: Probability = Favourable Cases/Total number of outcomes

Given question: 100 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.

(Table has been attached in the question already.)

What is the probability of germination of

i. more than 60 seeds in a bag?

ii. 99 seeds in a bag?

iii. more than 40 seeds in a bag?​

Solution: Total number of bags = 5

i) Favourable cases (more than 60 seeds in a bag) = 3

Reqd. Probability = Favourable Cases/Total number of outcomes

                              = $\boxed{\frac{3}{5}}$

ii) Favourable cases (99 seeds in a bag) = 1

Reqd. Probability = Favourable Cases/Total number of outcomes

                              = $\boxed{\frac{1}{5}}$

iii) Favourable cases (more than 40 seeds in a bag) = 5

Reqd. Probability = Favourable Cases/Total number of outcomes

                              = ${\frac{5}{5}}$

                             = $\boxed{1}$
