Answer:

Both

Claire

Andre

Neither

Step-by-step explanation:

We have to determine whether each point lies on Claire's line (blue) and whether it lies on Andre's line (black).

Point A is the intersection of both lines, hence the statement represents them both.

Point B only lies on Claire's line.

Point C is the start of Andre's line.

Point D is outside of both lines.

A 5 divided by 48 lottery involves choosing 5 of the numbers from 1 through 48 and a 4 divided by 35 lottery involves choosing 4
Anika [276]

Answer:

4/35 lottery is easier to win.

Step-by-step explanation:

For the 5/48 lottery, the winning probability is \frac{5}{48} ≈0.1042

For the 4/35 lottery, the winning probability is \frac{4}{35} ≈ 0.1143

Since \frac{4}{35}  >  \frac{5}{48} , the lottery where one chooses 4 of the numbers 1 through 35 is easier to win.
