Below is a probability tree outlining 3 steps to introducing a new product - a market research study, a test market initiative and a national marketing campaign. Calculate the probability of success of all three steps. Express probability as a decimal with two decimal places. Example 50% = .50 using the probability tree for Question 3, what is the combined probability of a new product appearing to be successful in a market research study as well as in a test market, and yet still failing in a national marketing campaign? Express probability as a decimal with two decimal places. Example 50% = .50
