a shirt is randomly drawn from a bag with 14 small shirts, 19 medium shirts, and 7 large shirts. event a: small event b: medium 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 shirts

$14 + 19+7=40$

Step2: Calculate P(A)

$P(A)=\frac{14}{40}$

Step3: Calculate P(B)

$P(B)=\frac{19}{40}$

Step4: Calculate P(A or B)

$P(A\ or\ B)=P(A)+P(B)=\frac{14}{40}+\frac{19}{40}=\frac{14 + 19}{40}=\frac{33}{40}=0.825\approx0.83$

Answer:

$0.83$
