(i) $4$ (ii) a number $<4$
Solution:-
In the question it is given that,
a die is thrown $450$ times
So, total number of times die thrown = $450$
- Number of times $4$ come on the die = $75$
$P(4$ will come up on die) = Number of times $4$ come up/Total number of times the die is
thrown
= 75/450
= 1/6
= $0.166$
- Number of times less than 4 come on the die
= $73$+$70$+$74$ =$217$
$P(<4$ will come up on die) = Number of times $(<4)$ come up/Total number of times
the die is thrown
= $\frac{217}{450}$
= $0.482$
