In a poker hand, John has a very strong hand and bets 5 dollars. The probability that Mary has a better hand is .04. If Mary had

mr_godi [17]

Answer:

When Mary raises the probability that she has a better hand is 0.273

Step-by-step explanation:

In the poker game it is given that the probability that Mary has a better hand than John is 0.04.

Let the event that Mary has a better hand than John be A.

Let the event that that Mary raises the stakes be B.

It is also given that if Mary has a better hand than John then she would raise with a probability of 0.9

Therefore p(B | A) = 0.9

If Mary has a poorer hand she will raise with a probability of 0.1

Therefore p(B | A') = 0.1

Given that Mary raises the probability that she has a better hand is given by

p(A | B)

$= \frac{p(A\cap B)}{p(B)}$ = $\frac{p(A)p(B | A)}{p(A)p(B | A) + p(A')p(B | A')} = \frac{(0.04 \times 0.9) }{(0.04 \times 0.9) + (0.96 \times 0.1)} = \frac{36}{36 + 96} = \frac{36}{132} = \frac{3}{11}$

= 0.273

So when Mary raises the probability that she has a better hand is 0.273

Effectus [21]

Answer:

Step-by-step explanation:

12.25 times 11 is 134.75

488 times 0.21 is 102.48

134.75 plus 102.48 equals 237.23

237.23 is closest to 232 which is B.
