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

What is the inverse of the function f(x) = 4x + 8? h(x) = x – 2 h(x) = x + 2 h(x) = x – 2 h(x) = x + 2
melomori [17]
F(x) = 4x + 8

Find x in terms of f(x):-

4x = f(x) - 8
x = (f(x) - 8 )  /  4

replace x by h(x) and f(x) by x

h(x) = (x - 8 ) /4

I cant get any of the choices

What past paper is this, can you please put a link to the question paper that this question came from :
neonofarm [45]

Using proportions, considering the ratios, it is found that Danil receives 65.33 euros.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

Danil, gabriel and hadley share some money in the ratios 3:5:9. Hence, the fraction of the total amount that Danil and Hadley receive are given by:

D = \frac{3}{17}n

H = \frac{9}{17}n

The amount of money that hadley receives is 196 euros, hence the total amount is found as follows.

196 = \frac{9}{17}n

n = \frac{196 \times 17}{9}

n = 370.22.

Hence, the amount received by Danil is given by:

D = \frac{3}{17}n = \frac{3}{17} \times 370.22 = 65.33
