3.a number not less than 3

Answer 1

Answer:

2/6

1/6

3/6 or 1/2 ..Thank you

Answer 2

Answer:

Each dice has 6 outcomes

1. when we throw dice, total outcomes will be 6

p(E) =number of outcomes / total number of outcomes

p(E>4)= 2/6 =1/3

2. Composite Number when it can be divided exactly

by a whole number other than itself

Among 1,2,3,4,5,6

4,6 are composite numbers

P(E) =2/6=1/3

3. P(E>=3) =4/6=2/3
