Answer:

63/3465

Step-by-step explanation:

A small pond contains nine catfish and two bluegill.

Total number of fish = 9 catfish + 2 blue hill

= 11 fishes

Probability of picking one catfish = P(C) = P(9/11)

Probability of picking one bluegill = P(B) = P(2/11)

If nine fish are caught at random, the probability that all of them are catfish is calculated as:

= P(9 Catfish) = 9/11 × 8/10 × 7/9 × 6/8 × 5/7 × 4/6 × 3/5 × 2/4 × 1/3

= 362880/19958400

Further simplifying to the simplest fraction:

= 189/10395

= 63/3465

A bag contains three red marbles, three green ones, one lavender one, one How many sets of five marbles include at least two red
dimaraw [331]

Answer with Step-by-step explanation:

The number of marbles are as under

3 red , 3 green , 1 Lavender total = 7

Now to select five marbles from a total of 7 marbles such that at least 2 marbles are included are the sum of the following cases:

1) We select 2 exactly 2 red marbles from 3 reds and the remaining 3 marbles are selected from 4 of other colours

Thus n_{1}=\binom{3}{2}\binom{4}{3}=\frac{3!}{2!}\cdot \frac{4!}{3!}=12

2)We select all the 3 red marbles and the remaining 2 are selected from the remaining 4 marbles

n_2=\binom{4}{2}=\frac{4!}{2!\cdot 2!}=6

Thus the total number of ways are n_1+n_2=12+6=18
