Question

(for me) hw 4

Complete the following probability distribution table for the discrete random variable X: Probability Distribution Table х P(X) 2 0.2 19 0.3 42 84 0.3 TIP Enter your answer as an integer or decimal number. Examples: 3,-4, 5.5172 Enter DNE for Does Not Exist, oo for Infinity

Answer 1

solution:- answer : 0.2

explanation:-

thefollowing probability distribution table for the discreate random variable x

we have know that the probabilities of random variables are equal to 1

=> 1 = 0.2+0.3+x+0.3

=> 1 = 0.8+x

=> x = 1 - 0.8

=> x = 0.2

table

x	P(x)
2	0.2
19	0.3
42	0.2
84	0.3
