Answer:

[tex]\begin{gathered} a)\text{ 13,983,816} \\ b)\text{ 15,180} \end{gathered}[/tex]

Explanation:

a) Here, we want to get the number of possible selections

Mathematically, that would be selecting 6 out of 49

We can calculate this using combination as follows

We have that as:

[tex]^{49}C_6\text{= }\frac{49!}{(49-6)!6!}\text{ = 13,983,816}[/tex]

b) What this means is that, winnings would only be paid to tickets with 4,5,6 in them while the other 3 numbers can be anything

What this means is that we would be selecting 3 out of 46 numbers

Mathematically, we use the combination rule again as follows:

[tex]^{46}C_3\text{ = }\frac{46!}{(46-3)!3!}\text{ = 15,180}[/tex]
