The probability that the bulb is defective is 0.04. The customer in the store randomly selects two of these bulbs. Find the probability that both bulbs will work.
1. According to the condition of the problem, it is said that the probability that the bulb will be defective is 0.04. Let’s calculate what is the probability that the light bulb is not defective.
p = 1 – 0.04 = 0.96.
2. Now let’s calculate the probability that two such bulbs, randomly chosen by the customer, will turn out to be operational.
p = 0.96 * 0.96 = 0.9216.
Answer: The probability that two bulbs, randomly selected by the buyer, will be serviceable is 0.9216.
