Answer:

0.095 or 9.5%

Step-by-step explanation:

Puncture → P(P) = 0.06

Smashed corner → P(S) = 0.04

Puncture and smashed corner → P(P and S) = 0.005

The probability that a randomly selected carton has a puncture or a smashed corner is given by the probability of a puncture, added to the probability of a smashed corner, subtracted by the probability of both:

$P(P\ or\ S) =P(P)+P(S) - P(P\ and\ S)\\P(P\ or\ S) =0.06+0.04-0.005\\P(P\ or\ S) =0.095=9.5\%$

The probability is 0.095 or 9.5%.

The correct question in the attached figure

step 1
calculate the different volumes
a) Volume of prism square base=x*x*y=x²*y
b) Volume of the cylinder=π*(z²)*y

the combined volume of the two figures=[x²*y]+[π*z²*y]

the answer is [y*x²]+[π*y*z²]
