.
We have to find the probability of germination of more than 35 seeds in a bag.
The number of germination of more than 35 seeds in a bag is given by,

= 40 + 48 + 42 + 39 + 41 = 210

The total number of seeds in a bag is given by,

n (S) = 40 + 48 + 42 + 39 + 41 = 210

For an event A,

P (A) = Number of Possible Outcomes Total Number of Outcomes

.
Substitute the known values within the formula,

= 210210 = 1

Hence, option 2 is correct.
