Assignment: Assign 5 - Discrete Probability Distributions Save Submit Questions Exercise 05.07 (Self-Test) Algorithmic 4. {Exercise 5.07 (Algorithmic)} The probability distribution for the random variable x follows. * f(x) 0.22 0.11 0.27 36 0.40 a. Is this a valid probability distribution? | Yes, because all f(x) are 20 and sum of f(x)=1 + b. What is the probability that x = 32 (to 2 decimals)? 0.27 C. What is the probability that x is less than or equal to 26 (to 2 decimals)? 0.33 d. What is the probability that x is greater than 32 (to 2 decimals)? 0.40

Explanation / Answer

a) Yes it is valid because sum of f(x) is 1
0.22+0.11+0.27+0.4 =1

b) P(x=32) from the table is 0.27

c) P(x<=26) =P(x=21)+P(x=26) =0.22+0.11 =0.33

d) P(x>32) =P(x=36) =0.40
