Question 1209958
This is a case of Binomial Probability distribution.
Here n=14, x>=3 and p=0.55. 1-p = 1-0.55 = 0.45
Now use the formula to calculate probability:
P(X>=3) = P(3)+P(4)+ -----+P(14)
This calculation becomes very lengthy, hence you may want to use a table or t technology( a calculator or software) I used an online probability calculator
P(X>=3) = refer to the picture attached.
