Poisson Formula finding lamina?

28 Views Asked by At

A microprocessor manufacturing facility produces 300 microprocessors per hour. The probability that an individual chip is faulty is 0.01. Calculate the probability that in a given hour's production:

a) Two chips are faulty

To find $\lambda$ I multiply

0.01*300 = 3

I am not sure though if I have to take the time into account(1 hour(60))?

Or if the question takes this into account.

Then finding P(2 microchips)

$3^2$* $e^{-3}$ / 2! = .22

But this seems awfully high to me 22% are my calculations off??
