Answer:
35
Step-by-step explanation:
the pattern is +2 so the answer is 35
We take 2 marbles from 20 marbles and the total ways is 20x19:2=190
But we need only 2 red marbles and the ways is 14x13:2=91
And finally we do the division 91:190=91/190 is the probability we need
The first sentence is irrelevant information, you can ignore that!
There are 20 players. Each player paid the <em>same amount. </em>
In total, they payed $500,000.
We need x, the amount a single player pays. x times 20 will give us 500,000. This gives us the equation 20x=500,000
Divide both sides by 20 to isolate the variable.
x=25,000
