SOLUTION-
NO OF WORK RELATED INJURIES ~ POISSON(3.5)
A.) THE PROBABILITY MASS FUNCTION FOR A POISSON DISTRIBUTION WITH PARAMETER IS,
P(X=x) =
B.) P( NO WORK RELATED INJURY)
= P(X=0)
=
= 0.0302
C.) P( ATLEAST TWO INJURIES OCCUR)
= P( X>=2)
= 1 - P(X<2)
= 1 - (P(X=0) + P(X=1))
= 1 -
= 1 - (0.0302 + 0.1057)
= 1 - 0.1359
= 0.8641
