A machine contains 125 gumballs if the probability of getting a red gumball is 3 over 5 what is the probability of not getting a red gumball?

What is the probability of drawing a black 7 followed by a red queen from a pack of playing cards?
There are two black 7's and two red queen's in a standard deck of playing cards. The probability of drawing a black 7 is 2 in 52, or 1 in 26, or about 0.038. The probability of drawing a red queen from the remaining 51 cards is 2 in 51, or about 0.039. The probability, then, or drawing a black 7 followed by a red queen is (2 in 52) times (2 in 51), which is 4 in 2652, or 2 in 1326, or about 0.00151.
What is the probability of drawing a red queen in a pack of playing cards?
The probability of drawing a red queen in a complete package of playing cards (ignoring jokers) is 1/26 or approximately 3.8%. There are 26 red cards in a deck of 52 cards. There are 2 red queens in those 26 red cards (one queen of diamonds and one queen of hearts). SO: 2 / 52 = 1 / 26 = approximately 3.8%.
What is the probability of getting a red card and a red card assuming the red card is replaced?
The probability of drawing two red cards with replacement is (1 in 2)2 or (1 in 4) or 0.25
