Sample space={5 B + 6 R + 9 G} = 20 (all possible outcomes
Favorable outcome ={6 R} = 6
P(1st Drawing R) = 6/20 = 3/10
Once drawn and not replaced the total remaining marble = 19 and within the 19, there are 5 Red left. So
P(2nd Drawing R) = 5/19
P( 1st AND 2nd R) = (3/10)x(5/19) = 3/38 = 0.0789

- All angles in a triangle add up to 180°
Step-by-step explanation:
<u>Step 1: Define</u>
3(x + 7)° = 63°
3(x + 7)° + 63° + y° = 180°
<u>Step 2: Solve for </u><em><u>x</u></em>
- Divide 3 on both sides: x + 7 = 21
- Subtract 7 on both sides: x = 14
