The probability of A or B occurring is given by P(A or B) = P(A) + P(B) - P(A and B) = 0.38 + 0.33 - 0.24 = 0.47.

If P(A)=0.38,P(B)=0.33, and P(A and B)=0.24, find P(A or B). \text { If } P ( A ) = 0.38 , P ( B ) = 0.33 \text {, and } P ( A \text { and } B ) = 0.24 \text {, find } P ( A \text { or } B ) \text {. } If P(A)=0.38,P(B)=0.33, and P(A and B)=0.24, find P(A or B).

$\text { If } P ( A ) = 0.38 , P ( B ) = 0.33 \text {, and } P ( A \text { and } B ) = 0.24 \text {, find } P ( A \text { or } B ) \text {. }$
