Answer:
There are 3478761 ways to select the first 5 numbers
Step-by-step explanation:
As understood from the statement of this problem we assume that it does not matter the order in which the first 5 white balls are selected.
In this case it is a combination.
So, what we want to know is how many ways you can choose 5 white balls out of 55.
Then we use the formula of combinations:

Where you have n elements and choose x from them.
Then we look for:

Applying the distance formula, the distance from from Tia's home to Lei's home = 14.4 units.
<h3>What is the Distance Formula?</h3>
The distance formula helps us to find the distance between two given coordinate points. It is expressed as,
.
Tia = (4, 8) = (x1, y1)
Lei = (12, 20) = (x2, y2)
Apply the distance formula to find the distance from Tia's home to Lei's home:
d = √[(12−4)² + (20−8)²]
d = √[(8)² + (12)²]
d = √(64 + 144)
d = √208
d ≈ 14.4 units
The distance from from Tia's home to Lei's home = 14.4 units.

Answer:
1/10,737,573
Step-by-step explanation:
The number of possible outcome is
47 combination 6
nCr=n!/(n-r)!r!
Then,
47C6 = 47!/(47-6)!6!
47C6=47!/41!6!
47C6=47×46×45×44×43×42×41!/41!6×5×4×3×2×1
47C6=47×46×45×44×43×42×/720
47C6=10737573
This the sample space of groups 6 numbers.
So to win a jackpot, you need to pick one of the possible outcome
P(winning jackpot)= 1/10,737,573
Wow, this result shows that it is not easy to win a jackpot from lottery games, it is on rare occasions to have the combine 6 numbers.
5ab/5b= a
-10b^2/5b= -2b
15bc/5b= 3c
Put it all together
Final answer: a-2b+3c
