A run of consecutive points on one side of the center line U

A run of consecutive points on one side of the center line. Uses a word (all lowercase) for the above questions. Give probability accurate to exactly four decimals; that is, for 0.12345 or 12.345%, give 0.1235. The probability of Signal 2 is:

Solution

A run of nine consecutive points on the one side of the center line.

The probability of a run of nine consecutive points on the one side of the center line is 0.5^ 9 =0.0020

And if considered both sides it will be 0.0020* 2= 0.0040

So probability of signal 2 is

P(signal 2)= 0.0040
