Probability of Neither of Events A or B Occurring Solution

Follow our step by step solution on how to calculate Probability of Neither of Events A or B Occurring?

FIRST Step Consider the formula
P((A∪B)')=1-(P(A)+P(B)-P(A∩B))
Next Step Substitute values of Variables
∴ P((A∪B)')=1-(0.5+0.2-0.1)
Next Step Prepare to Evaluate
∴ P((A∪B)')=1-(0.5+0.2-0.1)
LAST Step Evaluate
∴P((A∪B)')=0.4
