The average time between accidents in a factory is 16 weeks. Find the probability that more than 21 weeks pass between accidents.

P(x>21) = 0.2691 (Approx)

Step-by-step explanation:

Given:

Average accident = 16 week

Find:

Probability [more than 21 weeks pass]

Computation:

Exponential [λ] = 1/mean

λ = 1/16

P(x>21) = e^{-λx}

P(x>21) = e^{-(1/16)22}

P(x>21) = 0.2691 (Approx)

40% off the regular price is the correct answer.
