Step-by-step explanation:

There are 6 girls and 7 boys in the class. 10 players can be selected in

different ways.

1. A team of 10 players with 4 boys includes 6 girls.

- possible ways to choose 4 boys.

- possible way to choose 6 girls.

2. A team of 10 players with 6 boys includes 4 girls.

- possible ways to choose 6 boys.

- possible ways to choose 4 girls.

3. The probability that a randomly chosen team includes 4 or 6 boys is

square root of 36/6 = 2.449489743

square root of 16/6 = 1.632993162

square root of 6 = 2.449489743

the answer is square root of 16/6 because the square root of 36/6 is the same answer as square root of 6 = 2.449489743
