Find the cube root of the numbers
Lets put ti this way:
P[1st serve good & wins point] = 60% * 70% = 42% = A
<span>P[2nd serve good & wins point] = 40% * 76% *57% = 17.328% = B </span>
<span>1. P[win point] = A+B = C = 59.328% <------- </span>
<span>2. P[1st serve good | win point ] = A/C = 42 / 59.328 = 0.707 or 70.7%
Please </span><span>remember that 2nd serve come into use only if 1st serve is not good</span>
4 thousands equals 40 hundreds.
Normalmente, el fracaso se asocia con el valor 0 y el éxito con el 1. Se nombra como Be(p), donde p(X=1) = p es la probabilidad de obtener éxito y p(X=0) = q = 1-p la probabilidad obtener fracaso.
