Question 304684: this is the problem question:
Recently study of cardiovascular Risk Factors reports that 30% of Adults meet the Criteria for Hypertension if 15 adults are assessed what is the Probability that:
A. Exactly 5 meet the Criteria for Hypertension?

B. None meet the criteria for Hypertension?
c. Less than or equal to 7 meet the Criteria for Hypertension?

does it related to using the proability?

Recently study of cardiovascular Risk Factors reports that 30% of Adults meet the Criteria for Hypertension. If 15 adults are assessed what is the Probability that:
A. Exactly 5 meet the Criteria for Hypertension?
P(x=5) = 15C5(0.3)^5(0.7)^10 = 0.2061
---------------------------------------------
B. None meet the criteria for Hypertension?
P(x=0) = 15C0*(0.3)^0(0.7)^15 = 0.0047
---------------------------------------------

c. Less than or equal to 7 meet the Criteria for Hypertension?
P(0<- x <=7) = binomcdf(15,0.3,7) = 0.95
