A game wheel has 38 slots numbered 1-38, respectively. Matt places a bet on the odd numbers and Julie places a bet on numbers 10
aivan3 [116]
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
