Unit VI asst help. 10. One parent who has sickle cell anemia and one parent who is normal have a child. Construct a Punnett square and find the probability that the child is a carrier of sickle-cell anemia. A person with two sickle­cell genes will have the disease, a person with only one sickle­cell gene will be a
carrier of the disease, and a person with no sickle­cell genes will be normal. Denote the sickle­cell gene by s and the normal gene by n. Use lowercase letters to indicate that neither s nor n is dominant.
Complete the Punnett square below.

Cystic fibrosis is a serious inherited lung disorder that often causes death in victims during early childhood. Because the gene for this disease is recessive, two apparently healthy adults, called carriers, can have a child with the disease. We will denote the normal gene by N and the cystic fibrosis gene by c to indicate its recessive nature.
a. Construct a Punnett square to describe the genetic possibilities for a child who has one normal parent and one who is a carrier of cystic fibrosis.
b. What is the probability that this child will be normal?

A college administration has conducted a study of196 randomly selected students to determine the relationship between satisfaction with academic advisement and academic success. They obtained the following information: Of the 64 students on academic probation, 29 are not satisfied with advisement; however, only 19 of the students not on academic probation are dissatisfied with advisement. What is the probability that a student selected at random is on academic probation and is not satisfied with advisement? The probability is (Round to two decimal places as needed.) 21.We are drawing a single card from a standard 52­card deck. Find the following probability.
P(nine | nonface card)
The probability is (Type an integer or a simplified fraction.) 25. A pair of dice is rolled three times. Find the probability of rolling an odd total exactly once.
The probability that an odd total is rolled exactly once is (Round to three decimal places as needed.) 26. Find the probability, P(N∩R), associated with the tree diagram. What is P(N∩R)? (Round to the nearest hundredth.) 28. Imagine a subject is taking part in a study to test a new cold medicine. The probability that the subject
is taking drug A is 20%, that it is drug B is 20%, and that it is drug C is 60%. From past clinical trials, the probabilities that these drugs will improve his condition are A (10%), B (50%), and C (50%). What is the probability that he will improve?
The probability is (Type an integer or decimal)
