Transcribed Image Text:Given the cumulative distribution function of a discrete random variable X:
x< 0.2
0.2
0.2 < x< 0.4
0.4 S x< 0.6
a
F(x) =
0.6
0.6 < x< 0.8

x21
If P(0.2 < X < 0.6) = 0.1 and P(0.6 <x < 1) = 0.6, then:
a=0.3 and b=0.9
O None of other options
O a=0.3 and b=0.7
O a=0.4 and b-D0.8
