Answer:

Probability ≈ 0.4762

Step-by-step explanation:

See explanation below;

[tex]Total Number of Outcomes - 10C4,\\10 ! / 4! * ( 10 - 4 ),\\10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 / 4 * 3 * 2 * 1 * 6 * 5 * 4 * 3 * 2 * 1,\\\\Total Outcomes = 210,\\\\Number of Outcomes - 5C2 * 5C2,\\5C2 = 5 * 4 * 3 * 2 * 1 / 2 * 1 * ( 3 * 2 * 1 ),\\\\Number of Outcomes - ( 10 )^2 = 100,\\\\Conclusion; Probability = 100 / 210 = 0.4762[/tex]

Solution; Probability ≈ 0.4762
