Step 1: Determine the total number of bulbs and the number of bad bulbs. There are 20 bulbs in total, and 5 of them are bad. Step 2: Calculate the number of good bulbs. Number of good bulbs = Total bulbs - Bad bulbs = 20 - 5 = 15 Step 3: Calculate the probability of drawing a good bulb. P(good bulb) = Number of good bulbsTotal number of bulbs = (15)/(20) = (3)/(4) The probability of drawing a good bulb is (3)/(4). Step 4: Calculate the probability of drawing a bad bulb. P(bad bulb) = Number of bad bulbsTotal number of bulbs = (5)/(20) = (1)/(4) The probability of drawing a bad bulb is (1)/(4). That's 2 down. 3 left today — send the next one.
