selects a piece of candy and eats it (so it is NOT replaced!) Then selects a piece of candy and eats it. Find the probability of
e-lub [12.9K]

Question:

There are 30 candies in a box, all identically shaped. 5 are filled with coconut, 10 with caramel, and 15 are solid chocolate.

You randomly select a piece of candy and eat it (so it is NOT replaced!), then select a second piece. Find the probability of each event

(a) The probability of selecting two solid chocolates in a row.

(b) The probability of selecting a caramel and then a coconut candy.

Answer:

(a) P(Chocolates) = \frac{7}{29}

(b) P(Caramel\ and\ Coconut) = \frac{5}{87}

Step-by-step explanation:

Given

Coconut = 5

Caramel = 10

Chocolate = 15

Total = 30

For probabilities without replacement, 1 is subtracted after the first selection.

So, we have:

Solving (a): Two solid chocolates

This is calculated as:

P(Chocolates) = P(First\ Chocolate) * P(Second\ Chocolate)

P(Chocolates) = \frac{n(Chocolate)}{Total} * \frac{n(Chocolate) - 1}{Total - 1}

P(Chocolates) = \frac{15}{30} * \frac{15 - 1}{30 - 1}

P(Chocolates) = \frac{15}{30} * \frac{14}{29}

P(Chocolates) = \frac{1}{2} * \frac{14}{29}

P(Chocolates) = \frac{7}{29}

Solving (a): Caramel and Coconut

This is calculated as:

P(Caramel\ and\ Coconut) = P(Caramel) * P(Coconut)

P(Caramel\ and\ Coconut) = \frac{n(Caramel)}{Total} * \frac{n(Coconut)}{Total - 1}

P(Caramel\ and\ Coconut) = \frac{10}{30} * \frac{5}{30- 1}

P(Caramel\ and\ Coconut) = \frac{10}{30} * \frac{5}{29}

P(Caramel\ and\ Coconut) = \frac{1}{3} * \frac{5}{29}

P(Caramel\ and\ Coconut) = \frac{5}{87}

Which Iink between two elements could you remove from the relation so that becomes a function?
OLEGan [10]

Answer:

Either (3,b) or (3,e) must be removed to form the above relation to be function.

Step-by-step explanation:

Given the relation between the elements of domain and range. we have to remove the link between two elements so that relation becomes a function.

A function is a relation in which each element in domain set maps into only one element of range set i.e one element can never have two images in range set.

Here, the element 3 in domain set maps into two element b and e in range set. Therefore, to form a function one link must be removed either

f(3)=b or f(3)=e

Hence, either (3,b) or (3,e) must be removed to form the above relation to be function.
