Answer:
O
Step-by-step explanation:
Probability ( 1 blue marble and 3 green marbles) = ( Blue, green, green, green) + ( green, blue, green, green) + ( green, green, blue, green) + ( green, green, green, blue) = { (8/13) × (5/12) × (4/11) × (3/10) } + { (5/13) × (8/12) × (4/11) × (3/10) } + { (5/13) × (4/12) × (8/11) × (3/10) } + { (5/13) × (4/12) × (3/11) × (8/10) } = (4/143) + (4/143) + (4/143)+ (4/143) = 16/143

Answer:
true
Step-by-step explanation:
given
= 
( cross- multiply )
4x = 40 ( divide both sides by 4)
x = 10
1. Similarity ratio: ΔMON : ΔJOK = 4 : 3
2. Theorem to justify similarity: SAS.
.. MO = 4/3 JO
.. ∠O = ∠O
.. NO = 4/3 KO
3. Similarity statement: ΔMON ~ ΔJOK by SAS.
