u have to find the probability?? like we find it in normal distribution but there is a modulus|X-160|.. which is the problem!!
so 160 is the mean ?
and the value should be less than 10 ?

u hav C3 then u can understand easily!
|X-160| it will hav two equations for the modulus...1) X-160 2)-X+160 so according to 1) X-160<10 and 2) -X+160<10 after solving it the final eqn wil be P(150<X<170) and we have 2 find the probability(area) of this range...(mean=160 and standard deviation is 30)!
