Suppose that the proportions of blood phenotypes in a particular population are as follows: a b ab o 0.43 0.14 0.03 0.40 assuming that the phenotypes of two randomly selected individuals are independent of one another, what is the probability that both phenotypes are o? (enter your answer to four decimal places.) what is the probability that the phenotypes of two randomly selected individuals match? (enter your answer to four decimal places.)

a) 0.1600

b) 0.3654

Step-by-step explanation:

a) The samples are independents, so:

P(O1∩O2)=P(O1).P(O2)=0.40*0.40=0.1600

b) P(A1∩A2)+P(B1∩B2)+P(AB1∩AB2)+P(O1∩O2)=

P(A1).P(A2)+P(B1).P(B2)+P(AB1).P(AB2)+P(O1).P(O2)=

0.43^2+0.14^2+0.03^2+0.4^2=0.3654

The answer will be A.$15.75

Step-by-step explanation:

Since we have a 5% shipping charge, the total cost will be the price of shipping + the shipping charge... so how do we find the shipping charge.  Well in math the word "of" means times, so to find 5% OF 15 we multiply...

5% x 15

We need to convert the percent to decimal in order to do the multiplication so divide it by 100 (move the decimal twice to the left)

.05 x 15 = .75

So the shipping charge is .75 or 75 cents.  We need to add it in to the original cost to find the total...

$15 + $0.75 = $15.75

The answer is A.$15.75
