Please give a step by step process: Use the data in the following table, which summarizes blood groups and Rh types for 100 typical people. These values may vary in different regions according to the ethnicity of the population. Group: O A B AB Rh Type: Positive 39 35 8 4 Negative 6 5 2 1 a) If one person is randomly selected, find the probability of getting someone who is group A or Group B. b) If one person is randomly selected, find ??(group B or type Rh+). c) If four of the 100 people are randomly selected, find the probability that they all have blood types Rh? by: i. Assuming that each selected subject is replaced before the subsequent selections are made. ii. Assuming that none of the selected subjects are replaced. Solution n =100 typical people Without replacement: a) P(Group A or Group B) = 43/100 = 0.43 b) P(P(group B or type Rh+) = P(group B) + P(Rh+)_P(both) = 8+86-6/100 = 0.88 c) Rh negative prob p = 14/100 = 0.14 Hence prob for x =4 in 100 is binomial prob = 100C4(0.14)4(0.86)96 d) With replacement a) 0.43 b) 0.88 c) (0.14)4\' Note that only c gives different answer..

1. Please help me with this.
Thank you The operation of differentiation does not apply to discrete-valued quantities, and thus
a frequency-differentiation property for the FS or DTFS does not exist. However, a frequency-
differentiation property does exist for the DTFT. Explain and comment supporting your
explanation with the proper equations.
Solution
Frequency differentiation property exists for dtft because it converts discrete in time domain to
continuous in frequency domain where as dtfs converts discrete in time domain to discrete in
frequency domain
