The probability is 3/12 or 1/4 because you add all of the marbles together which is 12 and then you know that there is 3 blue ones so that is why the probability is 3/12 or 1/4.

Answer:
Heya Here's the required Answer mate
Given
- Total number of marble = 10
- Blue marble = 7
- Green marble = 2
- Red marble = 1
So,
- Total outcomes= 10
- Fav outcomes = 1+2 = 3
- probability (no blue marble) = Fav outcomes/total outcomes
- = 3/10
Hence the probability is 3/10
Hope it helps
