Strands of copper wire from a manufacturer are analyzed for strength and conductivity. The results from 100 strands are as follows:
Strength Strength
High Low
high conductivity 74 8
low conductivity 15 3
Required:
a. If a strand is randomly selected, what is the probability that its conductivity is high and its strength is high?
b. If a stand is randomly selected, what is the probabilitythat its conductivity is low or strength is low?
c. Consider the event that a strand hs low conductivity andthe event that the strand has a low strength. Are these tow eventsmutually exclusive?
