Question

A die has six faces numbered from 1 to 6. It is rolled and number on the top face is noted. When this is treated as a random trail.
a) What are the possible outcomes ?
b) Are they equally likely? Why?
c) Find the probability of a composite number turning up on the top face.

Answer 1

a. 123456 are the possible outcome

b. yes they are equally likely. since a die is a cube

c, total no of composite no.=3

   total no. of outcomes      =6

   probability=3/6=1/2

Answer 2

Answer:

possible outcomes=1,2,3,4,5,6

total no. of possible outcomes=6

yes,all are equally likely because all faces have same chance of coming at top

favourable outcomes=4,6

p(getting a composite number)=2/6

=1/3
