Answer:

$P(n>55)=0.1357$

Step-by-step explanation:

From the question we are told that:

Sample size n=100

Sample space n'=36

Generally the equation for the mean number of times odds appears is mathematically given by

$\=x_o=hp$

$\=x_o=100*0.5$

$\=x_o=50$

Generally the equation for standard deviation is mathematically given by

$\sigma=(hp(1-p))^{1/2}\\\sigma=(50(0.5))^{1/2}$

$\sigma=5$

Therefore probability to make wrong decision P(n>55)

$P(n>55)=1-P(z55)=1-P(z55)=1-0.86$

$P(n>55)=0.1357$
