Question

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1. If a probability distribution 5 1 has probabilities and x, what is the value of X? 12' 6' 4 ОА. 1 O B. 1 / 2 C. 1 O O D. حاليا SUBMIT​

Answer 1

1 / 6

Explanation:

If the probability distribution has the probabilities :

5/12, 1/6, 1/4 and x

Then ;

The total sum of all the probabilities should be equal to 1 ;

That is ;

5/12 + 1/6 + 1/4 + x = 1

Lcm of 4, 6, 12 = 12

(5 + 2 + 3)/12 + x = 1

10/12 + x = 1

x = 1 - 10/12

x = 2 / 12

x = 1/6
