Answer 1

Answer #1

TOPIC:Exponential distribution.

- Define, x = The time between lightning strikes during a particular thunderstorm (in seconds) Xm Exp (with mean, x = 15 seco So, F(x) = f o ; xco. (net; x70 ~cdf of xi (Ang). We need to find & The time between) lightning, is below the average e = P(x
