You got the first part right
The theoretical probability is related to 1/2. A coin toss should always come up heads 1/2 the time and tails one 1/2 the time. So out of a class of 40 people, 20 people should flip (say) heads in theory and the other half of a class of 40 should flip tails 20 times.
Put more formally it looks like this.
P(sample) = Sample size * P(of it occurring once)
P(of it occurring once) = 1/2
Sample size = 40
P(sample) = 40 * 1/2
P(sample) = 20

If she took option two, she would be missing 3 bags of bark chippings and 3 trays of pansies with 10.75 left to spend.
Now, it is unknown what the price for a single bag or tray is however it seems that the bark chippings cost more than the pansies. If it seemed to be any option that worked, it would be option two where she can buy the rest seperate and have more to spend still.
However, she doesn't have enough to buy all the bags of bark chippings and pansies that she needs.
