Answer: 1.3≈1
Step-by-step explanation:
Expected Value of any scenario is the value that shows what to expect in a statistical analysis of a data presented before the analyser. In this case, to determine the expected value, we independently multiply each probability with its corresponding number of notification and sum up our answers. That is,
Expected value = (0.2 × 0) + (0.4 ×1) + (0.3×2) + (0.1×3) = 0 + 0.4 + 0.6 + 0.3 = 1.3≈1
