5. A die is rolled. Find the probability of getting a number greater than 5.
Please solve my problem ​

Answer 1

Answer:

8/50 is the answer 13/50, 20/50,

Answer 2

Answer:

1) 4/25th probability

2) 1/4th probability

3) 1/3rd probability

4) 1 probability.

5) 1/6th probability.

Step-by-step explanation:

1) 8 students play chess. If one student is selected at random, the probability that the selected student plays chess is 8/50 = 4/25th.

2) There are 13 diamonds in a pack of 52 cards. So the probability of getting a diamond card is 13/52 = 1/4th

3) The probability of getting a purple ball is 20/60 = 1/3rd.

4) All the numbers of the six faces of a die are less than 7. So the probability of getting a number less than 7 when you roll a die is 6/6 = 1.

5) Only one number (6) of the six numbers on each face of a die is greater than 5. So the probability of getting a number greaten than 5 when you roll a die is 1/6.

Hope it helps!
