a fish is randomly drawn from a barrel with 10 green fish, 9 blue fish, and 16 red fish. event a: green event b: blue p(a or b) =? hint: p(a or b) = p(a) + p(b) round your answer to the nearest hundredth.

Explanation:

Step1: Calculate total number of fish

$10 + 9+16=35$

Step2: Calculate $P(A)$

$P(A)=\frac{10}{35}$

Step3: Calculate $P(B)$

$P(B)=\frac{9}{35}$

Step4: Calculate $P(A\ or\ B)$

$P(A\ or\ B)=P(A)+P(B)=\frac{10}{35}+\frac{9}{35}=\frac{10 + 9}{35}=\frac{19}{35}\approx0.54$

Answer:

$0.54$
