Marketing estimates that a new instrument for the analysis of soil samples will be very successful, moderately successful, or unsuccessful with probabilities 0.3, 0.6, and 0.1, respectively. the yearly revenue associated with a very successful, moderately successful, or unsuccessful product is $10 million, $5 million, and $1 million, respectively. let the random variable x denote the yearly revenue of the product. determine the probability mass function of x.

X (millions)   1        5         10  

     P(x)        0,1      0,6     0,3

Step-by-step explanation:

In this case, the probability mass function of X is the function that relates the money produced for the product with the probability of obtain this profit of the product.

The mass function will be:

X (millions)   1        5         10  

     P(x)        0,1      0,6     0,3

This is a probability mass function  because the sum of the probabilities of each value is 1.  0.1+0.6+0.3=1
