In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 t

kramer

Answer:

$\frac{10}{53 \times 46 \times 26}$

Step-by-step explanation:

The probability of matching the number drawn on the gold ball is

$\frac{1}{46}$

The number of possible pairs of numbers from 1 to 53 is

$\binom{53}{2} = \frac{53 \times 52}{2} = 53 \times 26$

Choosing 5 numbers, you are choosing 10 different pairs:

$\binom{5}{2} = \frac{5 \times 4}{2} = 10$

Therefore the probability of correctly matching the drawn pair is

$\frac{10}{53 \times 26}$

Thus, the probability of winning (matching the pair AND the gold ball) is

$\frac{10}{53 \times 46 \times 26}$

Solve the system using substitution.

Alexeev081 [22]

Answer:

Option B that is (2,6) is correct

Explanation:

We have been given with system of equations

$X+Y=8$ and $Y=3X$

Here, we will substitute the value of $Y=3X$ in $X+Y=8$

We will get $X+3X=8$

Further simplification we will get to $4X=8$

Hence, the value of $X=2$

And now, substituting the value $X=2$ in $Y=3X$ we will get $Y=6$ .

Therefore, option B is correct.
