There are 6 girls and 7 boys in a class. a team of 10 players is to be selected from the class. match each scenario to its probability

125/286

Step-by-step explanation:

First we calculate the numerator of the desired probability:

"N(___)" means "The number of ways we can choose___)

N[ (3 girls AND 7 boys) OR (4 girls AND 6 boys) ]

The word "AND" suggests MULTIPLICATION, the word "OR" suggests ADDITION:

N(3 girls)*N(7 boys) + N(4 girls)*N(6 boys)

C(6,3)*C(7,7) + C(6,4)*C(7,6) = 20*1 + 15*7  = 125

8      48

11      66

15      90
