Tom and Alice work independently in an attempt to solve a certain problem (i.e. whether one of them solves it does not affect th

vladimir1956 [14]

Answer:

a) P ( At-least 1 solves correctly) = 0.55

b) P ( Tom / at-least 1) = 0.45454

Step-by-step explanation:

Given:-

- Probability that Tom solves the problem, pt = 0.25

- Probability that Alice solves the problem, pa = 0.4

- Both probabilities are independent

Find:-

(a) What is the probability that the problem will be solved by at least one person?

(b) If you find out later that the problem has been solved by at least one person, what is the conditional probability that Tom solved it?

Solution:-

a) The probability for at-least one of them either "Tom or Alice" or " Both" solve the problem correctly. We can determine the required probability by subtracting the Probability that neither of them solve the problem correctly:

P ( At-least 1 solves correctly) = 1 - P ( Both answer incorrectly)

Where, the probability of both solving the questions incorrectly is:

P ( Both answer incorrectly) = ( 1 - pt)*( 1 - pa )

= ( 1 - 0.25)*(1 - 0.4 ) = 0.75*0.6

= 0.45

Hence, the required probability is:

P ( At-least 1 solves correctly) = 1 - 0.45

= 0.55

b) The conditional probability associated with Tom solves the question given that at-least one of them solved can be expressed as:

P ( Tom / at-least 1) = P ( onlyTom + Both solve) / P( at-least 1 solves)

- The probability that only Tom solves is Tom answers correctly and Alice answers incorrectly:

P ( Only Tom solves) = pt*(1-pa)

= 0.25*(0.6)

= 0.15

- The probability that Both solve is Tom answers correctly and Alice also answers correctly:

P ( Both answer correctly) = pa*pt

= 0.25*0.4

= 0.1

- The required conditional probability would be:

P ( Tom / at-least 1) = ( 0.1 + 0.15 ) / 0.55

= 0.25 / 0.55

= 0.45454

PLEASE HELP! A juice company gives prizes to anyone finding specially marked caps on its juice bottles. You and your friends buy

laiz [17]

The odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.

<h3>What is odds against?</h3>

In probability, the term odds against is the ratio of probability of non occurring a favorable event to the probability of occurring a favorable event. It can be given as,

$\text{odd against}=\dfrac{P(\overline A)}{P(A)}$

Here, $P(\overline A)$ is the probability of not occurring a favorable event, and P(A) is the probability of occurring a favorable event.

A juice company gives the prizes to anyone finding specially marked caps on its juice bottles. The 4 bottles have winning cap in 20 bottles. Thus, the probability of winning is,

$P(A)=\dfrac{4}{20}\\P(A)=\dfrac{1}{5}$

The probability of not winning is,

$P(\overline A)=1-\dfrac{1}{5}\\P=\dfrac{4}{5}$

Thus, the odd against the winning is,

$\text{odd against}=\dfrac{\dfrac{4}{5}}{\dfrac{1}{4}}\\\text{odd against}=\dfrac{16}{5}\\\text{odd against}=3.2$

Thus, the odds in favor of winning a prize in the contest of the juice company which gives prizes to anyone finding specially marked caps is 3.2.
