Errors in an experimental transmission channel are found when thetransmission is checked by a certifier that detects missing pulses. the number of errors found in a eight-bit byte is a random variablewith the following distribution: f(x) = { 0 x< 1 0.7 1 < = x < 4 0.9 4 < = x < 7 1 7 < = xdetermine each of the following probabilities: (a) p(x < = 4) (b) p(x > 7)(c) p(x < = 5) (d) p(x > 4)(e) p(x < = 2)
