Question

Probability that all 6faces of a dice appear atleast once

Answer 1

let S be the sample space for the dice.

therefore, S={1, 2,3,4,5,6}

n(S) =6

event: A=all 6faces of die appear at least once.

A={1, 2,3,4,5,6}

n(A)=6

p(A)=n(A)/n(S)

p(A)=6/6

P(A)=1

The probablity that all 6 faces of a die is 1 Or 100%
