We need to find the question for the probability of selecting a number is 3/10.
There could be many questions, but we need to cnostruct a question so that the probability of seelcting a number is 3/10.
So, one of the question could be:
Find the probability of selecting a number divisible by 3 from first ten natural numbers.
As there are are 3 three numbers divisble by 3 in first ten natural numbers.
So the probabily of selecting a number divisible by 3 from first ten natural numbers will be:
