Probability of Event A or B Occurring Solution

Follow our step by step solution on how to calculate Probability of Event A or B Occurring?

FIRST Step Consider the formula
P(A∪B)=P(A)+P(B)-P(A∩B)
Next Step Substitute values of Variables
∴ P(A∪B)=0.5+0.2-0.1
Next Step Prepare to Evaluate
∴ P(A∪B)=0.5+0.2-0.1
LAST Step Evaluate
∴P(A∪B)=0.6
