Answer:

0.2,0.2,0.6

Explanation:

Given that a continuous random variable is uniformly distributed between 150 and 250.

We know that a uniform distribution between (a,b) has pdf as

$(1)/(b-a ) \\=(1)/(100) ,150\leq x\leq 250$

a) the probability a randomly selected value will be greater than 230

=
$(250-230)/(250-150) \\=0.20$

b) the probability a randomly selected value will be less than 170

=
$(170-150)/(250-150)\\=0.20$

c) the probability a randomly selected value will be between 170 and 230

=
$(230-170)/(250-150)\\=0.60$
