14 black balls and 6 white balls are placed in an urn. Two balls are then drawn in succession. What is the probability that the

QveST [7]

Answer:

$Probability = 0.30$

Step-by-step explanation:

Given

Represent Black with B and White with W

$B = 14$

$W = 6$

Required

Probability of the second selection being white

This means that: The first selection could be white or black but the second must be white.

This probability would be represented as thus:

$Probability = (P(W)\ and\ P(W))\ or\ (P(B)\ and\ P(W))$

And it is calculated as:

$Probability = (\frac{n(W)}{Total} * \frac{n(W)-1}{Total - 1}) + (\frac{n(B)}{Total} * \frac{n(W)}{Total - 1})$

Notice that, the second selection has total -1 has its denominator. This is so because, the first selection was made without replacement

So, the formula becomes

$Probability = (\frac{6}{20} * \frac{6-1}{20- 1}) + (\frac{14}{20} * \frac{6}{20- 1})$

$Probability = (\frac{6}{20} * \frac{5}{19}) + (\frac{14}{20} * \frac{6}{19})$

$Probability = \frac{30}{380}+ \frac{84}{380}$

$Probability = \frac{30 + 84}{380}$

$Probability = \frac{114}{380}$

$Probability = 0.30$
