The probability of the first pick to be a boy is 10/25.
Let S be the sample space and E be the event of selecting 1 girl and 2 boys.
n(S)=number of ways selecting students of 25.
=²⁵C₃
=25·24·23/3·2·1
=2300
n(E)=(¹⁰C₁·¹⁵C₂)
=[10·(15·14)/2·1
=10500
P(E)=n(E)/n(S)=1050/2300=21/46
Answer:
7 6/7 or 7.8571429
Step-by-step explanation:
There is 8 ounces to a cup and 2 cups to a pint
so 24/8=3cups
so now we have 3 cups
3/2=1 1/2
1 pint and 1 cup is the answer
Price before tip "b" of Kia’s dinner is $ 35
<h3><u>Solution:</u></h3>
Given that kia dinner bill is $ 40.25 which inclused a 15% tip
To find: price before tip "b" of Kia’s dinner
Let us first find the tip amount paid by Kia
Let "b" be the dinner bill before tip
Given that dinner bill is $ 40.25 which inclused a 15% tip
So, 15 % of "b" is the tip amount paid
tip amount paid = 15 % of "b"
Now we can say,
<em>Dinner bill including tip = dinner bill before tip + tip paid</em>
$ 40.25 = b + 0.15b
40.25 = 1.15b
b = 35
Thus price before tip "b" of Kia’s dinner is $ 35
