Question

a toy is randomly drawn from a barrel with 28 toy soldiers, 16 model cars, and 6 model trains. event a: model car event b: model train 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 toys

$28 + 16+6=50$

Step2: Calculate P(A)

$P(A)=\frac{16}{50}$

Step3: Calculate P(B)

$P(B)=\frac{6}{50}$

Step4: Calculate P(A or B)

$P(A\ or\ B)=P(A)+P(B)=\frac{16}{50}+\frac{6}{50}=\frac{16 + 6}{50}=\frac{22}{50}=0.44$

Answer:

$0.44$
