Answer 1

Answer #1

Solution-:

The possible outcomes for rolling a 12 sided die once (assuming the die has values 1-12) is presented below in the sample space S:

$S = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12\}.$

$\therefore n(S)=12$

Let, Event A: Sample space not having 5 number on upward face

$A = \{1,2,3,4,6,7,8,9,10,11,12\}$

$\therefore n(A)=11$

Therefore, the required probability is = Number of times event A occured Number of times expriment performed

$=\frac{n(A)}{n(S)}=\frac{11}{12}=0.92$

Therefore, the required probability is 0.92
