Order matters in case of permutations but does not matter in combinations.
Given:
Number of red marbles = 3
Number of white marbles = 2
Number of green marbles = 1
To find: probability of picking 4 marbles and getting one of each color
Solution:
Total number of outcomes = =
Number of favourable outcomes = 2 red, 1 white and 1 green marble + 1 red, 2 white and 1 green marble = =
So, probability of picking 4 marbles and getting one of each color = Number of favourable outcomes/Total number of outcomes =
The Answer is = 8x^4
Hope this helps! :)
8 + 8 = 16
16 - 1 = 15
or
7 + 7 = 14
14+1 = 15
Answer:
-5
Step-by-step explanation:
To find the common difference, take the second term and subtract the first term
-2 - 3 = -5
Check with the third term and the second term
-7 - (-2) = -7 +2 = -5
The common difference is -5
