The Red Cross regularly conducts Blood Drives throughout the country. They often conduct emergency drives when they are in need of rare blood types. Blood type AB-negative is the rarest type of blood. Only 0.6% of us have this type of blood. Suppose a random sample of 30 blood donors is obtained. What is the probability that at least 2 of them have blood type AB-negative? a. 0.013
b. 0.999
c. 0.986
d. 0.014
e. 0.0008

The probability is    

Step-by-step explanation:

From the question we are told that

     The proportion people with  Blood type AB-negative in the world  is p = 0.006

     The sample size is  n =  30

 Generally the distribution of people with  Blood type  AB-negative  follows a binomial distribution  

i.e  

and the probability distribution function for binomial  distribution is  

Here C stands for combination hence we are going to be making use of the combination function in our calculators  

   Generally the probability that at least 2 of them have blood type AB-negative is mathematically represented as

=>      

=>      

this is false ^.^ lol

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides
