Answer:
the frequency of individuals with Type B blood in the population is 0.1977
Explanation:
Given:
Frequency of A allele is p = 0.24
Frequency of the individuals with blood type O is r = 0.38
Question: What is the frequency of individuals with Type B blood in the population, fB = ?
You need to apply the Hardy-Weinberg Equilibrium:
p²+q²+r²+2pq+2pr+2qr = 1
Here,
p, q and r are the frequencies of the alleles
Calculating the frequency of the allele q:

q = 1-p-r = 1-0.24-0.6164 = 0.1436
Frequency of individuals with type B blood:

The waiter tears the raised part
of the straw wrapper a few inches from either end and he pulls until a piece of
the wrapper is entirely removed. The exposed part of the straw is what is then
placed in the drink, leaving the remaining wrapper for the customer to remove
himself. This will assure the customer that the waiter has not touched the straw
with bare hands. The part of the straw that has remained is called a straw
lace, or a drinking straw sleeve or a strawphylactic.
