Answer:
1• Maximum-Minimum
0.25-0.1= 0.15
so,0.15 is the range of variable x
2.P(x<4) =P(3)+P(1)
=0.2+0.1
=0.3
3.P(x>4) = P(5)+P(8)
= 0.25+0.15
=0.4 or 0.40
4.P(1<x<8) = P(1)+P(3)+P(4)+P(5)+P(8)
=0.1+0.2+0.3+0.25+0.15
=1 or 1.0
5.P(3<x<8) =P(3)+P(4)+P(5)+P(8)
=0.2+0.3+0.25+0.15
=0.9 or 0.90
HOPE IT HELPS YOU.
