a ball is randomly drawn from a box with 3 footballs, 9 baseballs, and 8 golf balls. event a: football event b: golf ball p(a or b) = ? hint: p(a or b) = p(a) + p(b) round your answer to the nearest hundredth.
Answer
Explanation:
Step1: Calculate total number of balls
$3 + 9+8=20$
Step2: Calculate P(A)
$P(A)=\frac{3}{20}$
Step3: Calculate P(B)
$P(B)=\frac{8}{20}$
Step4: Calculate P(A or B)
$P(A\ or\ B)=P(A)+P(B)=\frac{3}{20}+\frac{8}{20}=\frac{3 + 8}{20}=\frac{11}{20}=0.55$
Answer:
$0.55$
