An electronic product contains 53 integrated circuits. The probability that any integrated circuit is defective is 0.02, and the
Varvara68 [4.7K]

Answer: Hello!

Here you have 53 integrated circuits, each with a probability of 0.02 of being defective.

If only one of them is defective, then the electronic product doesnt work.

Then we need the calculate the probability in wich all the 53 circuits arent defective.

the probability for each one to not be defective is 1 - 0.02 = 0.98

And if i want to see the probability for all of them to work fine, then i need to do the product of all the probabilities, this is multiply 0.98 53 times, or:

0.98^{53} = 0.34275

rounding to the four decimal place, we have: 0.3428

Wich is a kinda small probability for our product to work.
