HELP CORRECT ANSWER GETS BRAINLIEST and 100 POINTS
if you have 3 pennies, 4 dimes,9 quarters, and 3 dollar bills, and you choose 2 of these items by random what's the chance the sum of those 2 items will be an odd number

28/57 or 0.4912

Step-by-step explanation:

3 penny, each = 1p

4 dimes, each dime = 10p

9 quarters, each quarter = 25p

3 dollar, each dollar = 100p

Total items: 3+4+9+3 = 19

Odd:

1 penny & 1 dime

1 penny & 1 dollar

1 quarter & 1 dime

1 quarter & 1 dollar

2[(3/19 × 4/18) + (3/19 × 3/18) + (9/19 × 4/18) + (9/19 × 3/18)]

= 28/57

= 0.4912280702
