Question

In a game of chance, a spinning arrow comes to rest at one of the numbers (1, 2, 3, 4, 5, 6, 7, 8, 9). All these are equally likely outcomes. Find the probability that it will rest at: 1) 5 2) an odd number 3) an even number 4) a number less than 10 5) a number greater than 3 *​

Answer 1

Answer:

1) 1/9

2) 4/9

3) 4/9

4) 1/1

5) 1/3

Step-by-step explanation:

1) 1/9

2) odd numbers in the data = 4 (excluding 1)

∴ Probability of getting an odd number = 4/9

3) even numbers in the data = 4

∴ Probability of getting an even number = 4/9

4) Numbers less than 10 in the data = 9

∴Probability of getting a number less than 10 = 9/9 = 1/1

5) Numbers greater than 3 in the data = 6

∴Probability of getting a number greater than 3 = 6/9 = 1/3
