Hello, that number before the parenthesis means we have to multiply the number outside the parenthesis for the one inside it.
So, the first one 9(1/3) it's easy. We can write 9 as 9/1 to semplify our work.
You have to cross multiply. When cross multiplying, you can simplify numbers. 9 and 3 can be both divided for 3.
You get 3/1 × 1/1 = 3
It equals to 3
Then, 4(2.6) = 4 × 2.6 = 10.4
2(-3) = +2 × (-3) = -6
When you multiply a positive number for a negative one, you'll always get a negative number.
Sum all the results.
3 - 10.4 - 6 = 3 - 10.4 - 6 = - 13,4
Final answer: -13,4

1 red marble out of 5 total marbles
1 red marble and 4 not red marbles
odds in favor means number of favorable outcomes : number of unfavorable outcomes
this basically means red marbles : not red marbles
1: 4
