Make a chart. a) Find the probability that the bulb is red. 12/20 b) If the bulb chosen is red, what is the probability that the bulb is defective? 5/12 c) What is the probability that the bulb is defective? 8/20 tow truck company near me cheap The first box (B 1) has 15 defective bulbs and the second has 5 defective bulbs. Suppose a box is selected at random and one bulb is picked out. a) What is the probability it is defective? b) Suppose the bulb we tested was defective. What is the probability it came from box 1. No. of defective bulbs = 4 = 4 No. of non-defective bulbs = 1 9 − 4 = 1 5 P ( bulb is not defective ) = total numbers of bulbs No. of non-defective bulbs = 1 9 1 5 One bulb is defective and other one is not, and probability for that would be 18C1 x 2C1 / 20C2 = 36/190. Now, probability of choosing both "Prob of choosing 2 non-defective bulbs" is not equal to "1 - (prob of choosing 2 defective bulbs) ". What you are missing here in the equation is the...PROBABILITY & STATISTICS (BT 401) Maximum Marks: 20 Time: I Hrs. All the Questions are compulsory.

What is the probability that it has (i) no defective bulb? (ii) defective bulbs less than 4 ? (iii) defective bulbs more than 3 but less than 6 ? May 29, 2018 · What is the probability that this bulb is not defective? Total number of bulbs left = 20 1 = 19 Number of defective bulbs = 4 Number of non-defective bulbs = 19 4 = 15 P (getting a non-defective bulb) = ( )/( ) = 15/19 EXAMPLE 1.4 If we are making bolts with a machine, the result of the experiment is that some may be defective. Thus when a bolt is made, it will be a member of the set {defective, nondefective}. EXAMPLE 1.5 If an experiment consists of measuring “lifetimes” of electric light bulbs produced by a company, then griffin armament m4sdk for sale -8Ls
