<span>You are given circle R that has a radius of 6 inches. And then you are given points S, T, and U that lie on circle R, clockwise in alphabetical order. Also you are given m∠TRS = 98°and you are asked to find the m∠TUS. To solve this, you have to draw the circle first.
Draw a circle with R being a point at the center of it. Then place the points S, T and U around the circle. So that would mean any point, S, T and U that connects on R would have a value of 6 inches. Also, these are your radius.
You also know that m</span>∠TRS = 98°. You know that the circle, if you will base your angle from the center or its interior angle is just equal to 360°. To get the m∠TUS, subtract 360 to 98.
The sample space in the problem is 6 girls and 7 boys. If ten players are to be chosen composing of three or four girls, then for 3 girls:6C3 * 7C7 / 13C 10 = 0.06993 for 4 girls: 6C4 * 7C6 / 13C 10 = 0.3671 we add the two and the answer is 0.4371
