What is the probability

[From: ] [author: ] [Date: 11-10-29] [Hit: ]
the probability of selecting the defective bulb would be 1 out of 100, but there are 6 defective bulbs, so the probability of choosing a defective bulb goes up to 6 times 1 out of 100, or 6/100, which is 3/50.6/100 is the probability of grabbing a defective bulb from the lot.......
1.One light bulb is selected at random from a lot of 100 light bulbs, of which 6% are defective. What is the probability that the light bulb selected is defective?

Of the 100 light bulbs, 6% are defective, so that's 6 defective light bulbs. For this problem you don't need to choose one of those probabilities formulas because there is only one light bulb being selected. If there was 1 defective light bulb, the probability of selecting the defective bulb would be 1 out of 100, but there are 6 defective bulbs, so the probability of choosing a defective bulb goes up to 6 times 1 out of 100, or 6/100, which is 3/50.

Probability
Total number of defective bulbs over total number of bulbs
In this case 6% of a hundred gives us 6 defective bulbs so

6/100 is the probability of grabbing a defective bulb from the lot. Reduce the fraction.

3/50

6/100 = 0.06 ??
