Question

PLEASE HURRY, 100 POINTS!!

Another common bet in roulette is on the number being even or odd (not including 0 or 00). If the wheel is spun once, what is the probability of the outcome being an odd number?

Answer 1

Roulette wheel contains 1 to 36 numbers excluding 0 and 00

• Total nos =38

Total odd nos

{1,3,5,7,9,11,13,15,17,19,21,23,25,29,31,33,35}

• Total=18

Probability

• 18/38
• 9/19

Answer 2

9/19 or 47.4% (nearest tenth)

Explanation:

A roulette wheel is numbered 1 to 36 with 0 and 00.

Therefore, there is a total of 38 evenly-spaced pockets.

The number of odd numbers from 1 to 36 is 18

(1, 3, 5, 7, 9, 11, 13, 15, 17, 19, 21, 23, 25, 27, 29, 31, 33, 35)

`\sf Probability\:of\:an\:event\:occurring = (Number\:of\:ways\:it\:can\:occur)/(Total\:number\:of\:possible\:outcomes)`

`\implies \textsf{Probability of odd number}= \sf (18)/(38)=(9)/(19)=47.4\%`
