a cookie is randomly drawn from a box with 4 small cookies, 13 medium cookies, and 8 large cookies. event a: medium event b: large 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 cookies

$4 + 13+8=25$

Step2: Calculate P(A)

$P(A)=\frac{13}{25}$

Step3: Calculate P(B)

$P(B)=\frac{8}{25}$

Step4: Calculate P(A or B)

$P(A\ or\ B)=P(A)+P(B)=\frac{13}{25}+\frac{8}{25}=\frac{13 + 8}{25}=\frac{21}{25}=0.84$

Answer:

$0.84$
