Question

three coins are tossed simultaneously then the number of simple points n(S)=_________​

Answer 1

Answer:

When three coins are tossed,

Sample space S={HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

and n(S)=8

Answer 2

Step-by-step explanation:

Given: There are three colour dice of red, white and black color, These dice are placed in a bag

To find: Sample space for the given experiment

Explanation: A dice has 6 faces containing (1,2,3,4,5,6)

Let as Assume Red =R, White =W, Black =B

When dice is selected then rolled:

Red dice: S

R

={(R,1),(R,2),(R,3),(R,4),(R,5),(R,6)}

White dice: S

W

={(W,1),(W,2),(W,3),(W,4),(W,5),(W,6)}

Black dice: S

B

={(B,1),(B,2),(B,3),(B,4),(B,5),(B,6)}

∴ Total Sample space is

S=S

R

∪S

W

∪S

B

=
