The 2nd option from the top
binomial(16 + 7, 16) 2^(-(16 + 7)) = ((16 + 7)!)/(16! 7! 2^(16 + 7)) = 245157/8388608 ≈ 0.02922 ≈ 1/34.22
(assuming children are independent and male and female are equally likely)

Answer: 15=10+5
Step-by-step explanation:
Subtract 55 from both sides.
15-5=a
Simplify 15-5 to 10.
10=a
Switch sides.
a=10
