Question:hey please help answer these following questions for me.

Question #1) Let's assume we know that 1% of adults over the age of 60 have lung cancer, that 90% of adults who have lung cancer will test positive ( called a true positive), and that 8% of adults that don't have lung cancer will also test positive (called a false positive). what is the probability of actually having lung cancer if an adult test positive for lung cancer?

Question #2) select all the true statement about the normal probability distribution.

A) The area under the bell curve is 1 exactly.

B) The distribution has one mode and is bell shaped

C) THE random variable takes any value

D) The mean, median, and mode are equal

E) The distribution has one mode and has positive skew.

F) Standardizing an observation of any normal distribution allows the use of the standard normal (Z) distribution tables

G) The random variable does not take any value. it takes discrete values like the binomial distribution

Question #3) How many sequences of 3 things can be formed from 8 different things with replacement things and order is important?

Note: suppose a simple space has things a, b, and c . Twice , draw from the sample space and replace. The possible sequences formed are ( aa, ab, ac, ba, bb, bc , ca , cb , cc).
