A probability exp

Probability to its very basics is the ratio of ‘No. of favorable outcomes’ and ‘Total number of outcomes.’

i.e., P =

∴ It cannot be negative as both numerator and denominator are always positive.

Also, it cannot be greater than 1 (∵ number of favorable outcomes is always a subset of total outcome)

Now in this question the values of

(ii) (iv)- 0.78 (vi) 1.45 (ix) 112% are negative or greater than 1.

∴ they are not probability of any event.
