Know… for things like the lottery… if there are lottery tickets where you need to have a three digit number match exactly (like 492) to win.. what are your “odds” of winning? What about a four digit match ? What about a six digit match ??? (like 492048) … and yes, the four can be in any position,,, it could be in ALL the positions ? a. Is that the same as finding the probability of winning?

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
