Suppose a program has four conditional execution states (it does one of four things, depending on conditions of the input). At large enough scale, the program can be said to enter state 1 60% of the time, state 2 24% of the time, state 3 12% of the time and state 4 4% of the time. If the states have the following runtimes in milliseconds, give the 'expected value' for the runtime of the process: runtime(S,) = 50 ms, runtime(S2) = 172 ms, %3D runtime(S3) = 1400 ms, runtime(S4) = 3400 ms. %D
