2 different dice are thrown at the same time find the probability that the sum of the two numbers appearing on the top of that i c 7
Answers
Answer:
2/9
Step-by-step explanation:
(3,2)
(2,3)
(6,1)
(1,6)
(4,3)
(3,4)
(2,5)
(5,2)have sum 7
possible outcomes =8
total outcomes =36
probability =8/36
Therefore the probability that the sum of the two numbers appearing on top of the dice as '7' is '1/6'.
Given:
2 different dice are thrown at the same time.
To Find:
The probability of obtaining the sum of numbers appearing on the dice is '7'.
Solution:
The given question can be solved very easily as shown below.
Given that,
2 different dice are thrown at the same time.
The total number of outcomes = n(s) = 6² = 36
Number of favorable outcomes ( Getting '7' as sum from both dice ) = n(P) = (6,1), (1,6), (4,3), (3,4), (2,5), (5,2) = 6 ways
The probability of getting the sum as '7' from both the dice = n(P)/n(s) = 6/36 = 1/6
Therefore the probability that the sum of the two numbers appearing on top of the dice as '7' is '1/6'.
