Question

A dice is thrown once, what is the probability that it is a) at least 4 b) at most 4​

Answer 1

Answer:

ANSWER

We know that sample space S on throwing a dice is S=(1,2,4,5,6]

∴ Total number of cases (possible outcomes) n(S)=6

Event E: Getting a number greater than 4,

E={5,6}Number of favourable Gases =n(E)=2

∴P(E)=

n(S)

n(E)

=

6
