| Thank you for using Chegg | |||||
| Given a box with 11 marbels | |||||
| Probability to pick up red marbles (A) | = | 6/11 | |||
| Probability to pick up green marbles (B) | = | 3/10 | |||
| Probability to pick up yellow marbles © | = | 2/9 | 0.218182 | ||
| Now the marbels can be picked up in 3! Ordered ways i.e. RGY,GRY etc | |||||
| Total number of ways of picking up 3 marbles (D) | = | A*B*C*3! | = | 0.21818 | |
