There are (5 C 1) = 5! / (5 - 1)! = 5 ways of drawing a red marble, and (11 C 1) = 11! / (11 - 1)! = 11 ways of drawing any marble, so that the probability of drawing a red marble is 5/11.

After putting back the first marble, the probability of drawing another red is again 5/11.

So the probability of drawing 2 red marbles with replacement is (5/11)² = 25/121.

1. Jadyn started off his long division problem incorrectly. What is his mistake?
Anastaziya [24]

The mistake Jadyn made in the long division is

  • Mistake in subtraction
  • the first quotient

<h3>What is long division ?</h3>

Long division refers to a way of dividing large numbers

performing the long division correctly gives

divisor    dividend     quotient     multiplication    subtraction  new dividend

8             335              40               8 * 40 = 320     335 - 320       15          

8             15                 1                   8 * 1 = 8            15 - 8                7  

8             70                0.8               8 * 8 = 64      70 - 64                6

8             60                0.07             8 * 7 = 56       60 - 56               4

8             40                0.005           8 * 5 = 40       40 - 40               0

The quotient is then added as

40 + 1 + 0.8 + 0.07 + 0.005 = 41.875
