X 1 2 3 4
p(x) 0.40 0.20 0.15 ?
If the items are only 4. The total of the probability must be 1 or 100%
1 - 0.40 - 0.20 - 0.15 = 0.25
The probability of 4 is 0.25.
Dylan's conclusion is not valid, because Dylan did not account for the other items purchased, only bagels.

Answer:
The answer is C
Step-by-step explanation:
117 + 23 =140 and you have $140 in all so you spent it all
1/2 - 3/11
Set both denominators (bottom numbers) to 22, so multiply the numerator of 1/2 by 11, and multiply the numerator of 3/11 by 2.
1/2 is now 11/22
3/11 is now 6/22
So, our new question is now : 11/22 - 6/22
Because the denominators are the same, all you have to do is simplify the top numbers.
So, 11-6 = 5
Therefore, your answer is 5/22
