###### Question 34 (Textile Engineering & Fibre Science)

The number of neps in a carded web follows Poisson distribution with a mean of 100 per m^{2}. The probability that there is no nep in an area of 645 cm^{2} is

(A) | |

(B) | |

(C) | |

(D) |

###### Answer / Solution

By Poisson distribution-

Mean=100 per m2

Then no. of neps=?

Probability that there is no neps in an area 645 cm2=?

By Poisson distribution-

=

=

=

= Ans

Option A is correct.
