The probability that the sample of four balls contains two white balls and two red balls is 0.39.
Let E be an event a sample of selecting four balls from an urn are two red balls and two white balls.
According to the given question.
Total number of marbles in an urn = 17 + 20 = 37
Total number of white marbles = 17
Total number of red marbles = 20
Now, the number of ways of selecting four marbles form an urn =
And, number of ways of selecting 2 white and two red marbles =
As, we know that probability of an event is calculated by taking the ratio of total number of favorable outcomes to the total number of outcomes.
Therefore, the probability that the sample of four balls contains two white balls and two red balls is given by
⇒ P(E) = 5(19)(17)(16)/(37(3)(35)(17))
⇒ P(E) = 19(16)/37(3)(7)
⇒ P(E) = 304/777
⇒ P(E) = 0.39
Hence, the probability that the sample of four balls contains two white balls and two red balls is 0.39.

Answer:
Assuming you are asking for the Greatest Common Factor (GCF) of and
the answer is:
Step-by-step explanation:
To find the GCF we should first find the GCF of the coefficients 50 and 40 which is 10.
After factoring that out we need to take a look at the variable m. In monomial 1 we see that the highest exponent of m is 4 and in the second is 2. When finding GCF we take the smallest of the two exponents which is 2. Therefore the next part of our GCF monomial is m²
If we apply the same rule for n the smallest exponent is 7 resulting in the appending of to the answer
After combining each of these GCF of 40 and -50 (10), m^4 and m² (m²), and n^7 and n^10 (n^7) the answer is:
