Question 4 An insurance company offers its policyholders a number of different payment options. For a randomly selected policyholder, let X = the number of months between successive payments. The cdf of X is as follows: F(x)= 0, ifr <0 F(x)=0.3, if 0≤x<3 F(x)=0.55, if 3 6 Using just the cdf, compute P(3≤X ≤ 6). O 0.8 O 0.3 O 0.25 O something else O 0.5

An insurance company offers its policyholders a number of different payment options. For a randomly selected policyholder, let X = the number of
months between successive payments. The cdf of X is as follows:
F(x) = 0, if x < 0
F(x) = 0.3, if 0 ≤ x <3
F(x) = 0.55, if 3 ≤ x < 4
F(x)=0.8, if 4 ≤ x ≤ 6
F(x) = 1, if x > 6
Using just the cdf, compute P (3 < X < 6).
