how many ways are there to win the jackpot? how many ways are there to match 5 of 6 numbers? how many ways are there to match 4
musickatia [10]

The number of ways to  match 5 of 6 numbers is 6 ways

The number of ways to  match 4 of 6 numbers is 15 ways

The number of ways to  match 3 of 6 numbers is 20 ways

To calculate number of ways to match 5 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C5=\frac{6!}{(6-5)! . 5!}

6C5=\frac{6!}{(1)! . 5!}

6C5=\frac{6.5.4.3.2.1}{1.5.4.3.2.1}

6C5=\frac{6}{1}

6C5= 6 \ ways

∴ 6 ways are to match 5 of 6 numbers

To calculate number of ways to match 4 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C4=\frac{6!}{(6-4)! . 4!}

6C4=\frac{6!}{(2)! . 4!}

6C4=\frac{6.5.4.3.2.1}{2.1.4.3.2.1}

6C4=\frac{30}{2}

6C4= 15 \ ways

∴ 15 ways are to match 4 of 6 numbers

To calculate number of ways to match 4 of 6 numbers we have to use to formula:

nCr =\frac{n!}{(n - r)! . r !}

6C3=\frac{6!}{(6-3)! . 3!}

6C3=\frac{6!}{(3)! . 3!}

6C3=\frac{6.5.4.3.2.1}{3.2.1.3.2.1}

6C3=\frac{120}{6}

6C3= 20 \ ways

∴ 20 ways are to match 3 of 6 numbers

6. What is the greatest common factor of the following expression? *<br> 15y3 – 40y
Nady [450]

Answer:

I'm not sure what 15y3 is, but I'll take a guess.

If the only numbers are 15, 3, and -40, then the greatest common factor is 1.

If the only numbers are 15 and 3, then it's three.

If the only numbers are 15 and -40, it would be 5.
