The answer is the 4th choice
Odd numbers are of the from a(n)=a+d(n-1) where a=1 and d=2 so
a(n)=1+2(n-1)=2n-1 and we need the number of odds in the range 1 to 38
2n-1≤38
2n≤39
n≤19.5, so there are 19 odd numbers in [1,38]
And since Julie bet on two even numbers as well, the probability of getting an odd number or the two evens she picked is:
(19+2)/38
21/38
Answer:
28.5

I don't exactly know what's the answer. but I've just tried.if I'm wrong tell me the answers that I can try another method or you can just tell me you're wrong then I'll try again and send you the answer.I'm not pretty sure that this is the answer. and if I'm correct tell me I'm correct.
Answer:
The sum of x and y is 8.
Step-by-step explanation:
x+2y=10
x-2y=2
------------
2x = 12, so x = 6. Substituting 6 for x in the 2nd equation, we get:
6 - 2y = 2, or
4 = 2y, or y = 2. The solution is therefore (6, 2).
The sum of x and y is 6 + 2 = 8 (answer)
