Probability of Exactly One Event Occurring Solution

Follow our step by step solution on how to calculate Probability of Exactly One Event Occurring?

FIRST Step Consider the formula
P(Exactly One)=(P(A)⋅P(B')⋅P(C'))+(P(A')⋅P(B)⋅P(C'))+(P(A')⋅P(B')⋅P(C))
Next Step Substitute values of Variables
∴ P(Exactly One)=(0.5⋅0.8⋅0.2)+(0.5⋅0.2⋅0.2)+(0.5⋅0.8⋅0.8)
Next Step Prepare to Evaluate
∴ P(Exactly One)=(0.5⋅0.8⋅0.2)+(0.5⋅0.2⋅0.2)+(0.5⋅0.8⋅0.8)
LAST Step Evaluate
∴P(Exactly One)=0.42
