1. [46.66 Points] I DETAILS I WAMEFMAcs P.2.ooz. Check whether the given function is a probability density function. [f a function fails to be a probability density ' x} = x on [0, 5] 0 Yes, it is a probability function. O No, it is not a probability function because f(x) is not greater than or equal to II} for every x. O No, it is not a probability function because f(x) is not less than or equal to t} for every x. 5 O No, it is not a probability function because] f{x)dx :2 1. I] 5 O No, it is not a probability function because] flxldx = 1. o 2. [46.66 Points] DETAILS WANEFMACE P.2.008. Check whether the given function is a probability density function. [f a function fails to be a probability density ' f{x} = e" on [0, In 8] 0 Yes, it is a probability function. 0 No, it is not a probability function because f(x) is not greater than or equal to t} for every x. O No, it is not a probability function because f(x) is not less than or equal to E} for every x. O No, it is not a probability function because x) o'x at 1. I] In 8 O No, it is not a probability function because] x) dx = 1. I]
