<span>a. 72 And 115
7+2=9
1+1+5=7
not true that both are divisible by 3
b. 120 And 835
1+2=3
8+3+5=16</span>
<span><span>not true that both are divisible by 3
but, they're both divisible by 5! (0 or 5 at the end)
not relatively prime
</span> c. 201 And 735
2+1=3
7+3+5=15
both are divisible by 3!
d. 303 And 1041
3+3=6
1+4+1=6
both divisible by 3
so the answer is a </span>

Answer:

Step-by-step explanation:
From the given information:
The probability (p) of winning a bottle cap = 
The probability of not winning a bottle cap will be (q) = 1 - p


Since we are told that the winning is placed once on every sixth bottle
Then the required probability = P( of not winning the first purchase) × P( of not winning the second purchase) × P( of winning the third purchase)
