If X is the angle where the defect ocours, m.esured from a oference line, thon X can be modeled as a uniform random variable on the interval from 0 to 360 degrees. a) What is the b) What is the probability that the defect is found between 0 and 108 degrees or between bility that the defect is found between 0 and 108 degrees? 252 and 360 degrees? a) The probability is (Round to three decimal places as needed.) 01 b) The probability is Round to three decimal places as needed.)

Explanation / Answer

X~U(0,360)

A. P(0<X<108)=0.3

P(252<X<360)=0.3

B. P(0<X<108) or P(252<X<360)= 0.3+0.3=0.6
