Amanda [17]

Answer:

probability = 0.2517

Step-by-step explanation:

given data

boy kittens = 9

girl kittens = 6

choose kittens at random = 9

solution

total kitten are = 9 + 6 = 15

first we get here total no of probability that is

n(s) = 15 C 9

n(s) = \frac{15!}{9!(15-9)!}  

n(s) =5005

and

total way to chose 5 boy kittens is = 9 C 3

n(3) = \frac{9!}{3!(9-3)!}  

n(3) =  84

and

total way to chose 4 girl kittens is = 6 C 4

n(4) = \frac{6!}{4!(6-4)!}  

n(4) = 15

so

total way to chose 5 boy kittens and 4 girl kittens is

total way = 84 ×15  = 1260

so probability that the director chooses 5 boy kittens and 4 girl kittens is

probability = \frac{1260}{5005}  

probability = 0.2517

Andru [333]

Answer:

10.6

Step-by-step explanation:

The amount of salt in one liter is 1.2 ounces, meaning to make one pound (16 oz) it would take 13 1/3 liters of water.

For 2.5 pounds, it would be 2.5*16, or 40-- 40 liters for 2.5 pounds of salt.

40 liters in (U.S.) gallons is 40/ (approximately) 3.785 , or 10.5680, 10.6
