Everyday I go to Starbucks.

1) On any day, define the amount I spend at Starbucks as a random variable X

X. A salted caramel mocha is 6\$ and a regular coffee is \$2.50. Write out the sample space for this experiment. Write out X

X as a function of the outcomes in the sample space. Argue that X

X is a discrete random variable.

2) Suppose further, that I am now interested in the amount of times I buy a regular coffee in the next 10 days. What type of random variable is this? What is the probability I buy exactly 7 coffees over the next 10 days?

1) The possible sample space for X be {\$6, \$2.5}. ﻿ f ( X ) = { ​ 0 . 5 , X = \$ 6 ​ 0 .... View the full answer
