If the probability of a car starting on a cold morning is 0.6, and we have two such cars. What is the probability of at least one of the cars starting on a cold morning?

OPTIONS

  • 0.84
  • 0.81
  • 0.6
  • 0.36

ANWER

0.84

EXPLANATION

This question can be solved by using additive law of probability:(A u B)= P(A)+P(B)-P(A ∩ B)(A u B)= 0.6 + 0.6 – (0.6*0.6) = 1.2 – 0.36 = 0.84
