Assuming that the balls are not replaced;

= 5/42
(the numbers are decreasing in the denominator as you are presumably taking out the red balls. In the denominator, there is one less ball each time since you took out a red one).
Therefore, the probability of selected 4 red balls consecutively without replacement is 5/42.

Answer:
for number one, look at the screenshot attached, that should help
Step-by-step explanation:
5/8=.625 and 7/15=.466 repeating so 5/8 is a bigger fraction

You can set up a simple algebraic equivalent to find a number equivalent to 200 after being multiplied by 3 and added 11 to.
3x+11=200
3x=189
x=63
