Problem # 7. A missile can be accidentally launched if two relays A and B both have failed. The probabilities of failure of A and B are known to be 0.01 and 0.03, respectively. It is further known that if A fails then B is more likely to fail (specifically at probability 0.06). a) What is the probability of an accidental launch? b) What is the probability that A fails given that B fails?

1mile equals approximately 1.6 kilometers. which best approximates the number of miles in 6 kilometers?

Weekly wages at a certain factory are normally distributed with a mean of $400 and a standard deviation of $50. find the probability that a worker selected at random makes between $450 and $500

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
