Please explain the following using the formulas and steps. I do want the answer in the end so I can check my work, but I really want to LEARN how to solve these. Numbering the steps really help. I do not know which formula to use and how to apply them. Thank you so much!

Determine the following probability.

1) The probability of an individual having Type Oblood is 0.45.

What is the probability of having a blood type other than O?

Use the Empirical Rule (68-95-99.7) to answer the question.

2) The interest rate for the financing of a used car is on average 9% with a standard deviation of 3%.Assuming that interest rates for used car loans are normally distributed, approximately what percent of loans have an interest rate that is between 6% and 12%?

Find the indicated probability.

3) Ahotel has 20 rooms on the first floor, 60 rooms on the second floor, 40 rooms on the third floor, and 20 rooms on the fourth floor.

If a hotel room is assigned at random, what is the probability of getting a room on an odd floor?

Find the Indicated Probability

4) A survey of 150 people revealed that 115 people like ketchup on their hot dogs, 85 people like mustard on their hot dogs and 60 people like both.

What proportion of those surveyed like ketchup or mustard on their hot dog?

Find the indicated probability.

5) In general,the probability that a blood donor has Type A blood is 0.40.

Consider 8 randomly chosen blood donors, what is the probability thatexactly half of them have Type A blood?

Find theindicated probability.

6) IQ scores are known to be normally distributed with a mean of 100 and a standard deviation of 15.

What is the probability that a randomly selectedindividualhas an IQ score that is less than 120?

Find the indicated probability.

7) An insurance company has determined that the cost of a certain medical procedure varies according to a normal distribution with a mean of $800 and a standard deviation of $40.

If a new insurance claim comes in for this particular medical procedure, what is the probability the claim will be greater than $900?

Find theindicated probability.

8) IQ scores are known to be normally distributed with a mean of 100 and a standard deviation of 15.

What is the probability that a randomly selectedindividualhas an IQ score that is between 100 and 120?

Identify the z-score corresponding to the indicated percentile.

9) For the standard normal curve, identify the z-score that corresponds to the 33^rdpercentile.

a) -0.67

b) 0.6293

c) -0.44

d) 0.3707

PLEASE EXPLAIN HOW AND WHEN TO USE CERTAIN FORMULAS - IT WILL HELP SO MUCH THANK YOU
