Calculate the probability of getting four consecutive points

Calculate the probability of getting four consecutive points outside the 2 C zones. The probability of being in each C-Zone is 34% or 68%, so the probability of not being in the C-zones is 1- 0.68

Solution

probability of getting four consecutive points outside the 2 C zones= p^4

probability of being in 2C-Zone =0.68+0.34-0.68*0.34 =0.7888.

so,probability of not being in 2C-Zone= 1-0.7888 =0.2112 =p

so,

probability of getting four consecutive points outside the 2 C zones= p^4 =0.001989

note its not clearly mentioned if the probability of being in each C-Zone is 34% or 68% is for one point or 4 points. I have calculated it assuming that this probability is for 1 point.
