That's not quite what I got. What did you add up? (Remember you have to show your work for as long as you continue to want help!)duki said:

The probability of selecting a red ball from a box of 10 balls depends on the number of red balls in the box. If there are 3 red balls in the box, the probability would be 3/10 or 30%.
The probability of selecting a blue ball from a box of 20 balls would be 8/20 or 40%. This assumes that the balls are randomly mixed and there is no bias towards any particular color.
There are 56 different combinations of balls that can be selected from a box of 5 red balls and 3 blue balls. This can be calculated using the combination formula nCr = n! / (r!(n-r)!), where n is the total number of balls and r is the number of balls being selected.
The probability of selecting 2 red balls in a row from a box of 10 balls would depend on the total number of red balls in the box. If there are 3 red balls in the box, the probability would be (3/10) * (2/9) or approximately 6.67%.
The number of balls in a box can affect the probability of selecting a specific color in two ways. First, a larger number of balls means a larger pool to select from, which can decrease the probability of selecting a specific color. Second, if there are more balls of a specific color in the box, the probability of selecting that color would increase.
