The probability of at least one fatal accident in a year will be 0.083

It is given that the probability of an individual coalminer being killed in a mine accident during a year is 1/2400.

Therefore,

Let the event of a fatal accident be A.

P(A) = 0.000416

Now given that 200 miners are working in the mine.

Therefore the probability of someone getting killed will be

200xP(A) = 200 x 0.000416

= 0.08

Therefore the probability of at least one fatal accident in a year is 0.08
