Question

In a game of chance, a spinning arrow comes to rest at one of the numbers1, 2, 3, 4, 5, 6, 7, 8. All these are equally likely outcomes. Find the probability that it will rest at 1) a number greater than 2.(2) a number less than 9​

Answer 1

Answer:

1)¾ 2)1

Step-by-step explanation:

possible outcomes (S) = {1,2,3,4,5,6,7,8}

n(S)=8

1) a number greater than 2 :

Let 'E' be the event of getting a number greater than 2

E={3,4,5,6,7,8}

n(E) =6

P(E)= 6/8

= 3/4

2) a number less than 9 :

Let 'F' be the event of getting a number less than 9

F = {1,2,3,4,5,6,7,8}

n(F)=8

P(F)=8/8

= 1

Answer 2
