What if we draw three socks from the box instead. what is the probability that we draw a matching pair? (having all three socks

be the same color also counts as having a matching pair.)?

There is a chance of 1/16*1/15 that she gets the specific socks pair according to laws of probability and the counting principle but thats not how it will work over here.

As we should be guaranteed that she gets the number of socks she obviously must take out around 9 socks as we are taking the worst case scenario where all the socks that come out are the different ones so the ninth sock must match any of the others.

But if we draw three socks obviously the probability is 1/16*1/15*13/14 as we dont want the third one to be same. We can multiply the answer by 3 as it can be in three different orders.

Each person on a four-person relay team completed a race in approximately 18.1 seconds. How long did it take the relay team to f
likoan [24]

Answer:

72.4 seconds

Step-by-step explanation:

We are given that,

Time taken by each person in the team = 18.1 seconds

Number of members in the team = 4

It is required to find the total time taken by the team to finish the race.

Thus, the time taken taken = 4 × 18.1 = 72.4 seconds

Hence. the team finished the race in 72.4 seconds.

If a single card is drawn from a standard 52-card deck, what is the probability that it is an ace or a spade?
klasskru [66]

A 52-card deck is made up of an equal number of diamonds, hearts, spades, and clubs. Because there are 4 suits, there is a 1/4 chance to draw one of them, in our case, spades.

There are 4 aces in a 52-card deck, so the chance of drawing one is 4/52, or 1/13.

The question asks for the probability of drawing an ace or a spade. Because it uses the word "or," we add the probabilities together. This is because there is a chance of drawing either of the cards; it doesn't have to meet both requirements to satisfy the statement.

However, if the question were to say "and," we would multiply the two probabilities.

Let's add 1/4 and 1/13. First, we can find a common denominator. We can use 52 because both fractions can multiply into it (since the ratio came from a deck of 52 cards as well).

\frac{1}{4} -- > \frac{13}{52}

\frac{1}{13} -- > \frac{4}{52}

Now we can add them together.

\frac{13}{52} + \frac{4}{52} = \frac{13+4}{52} = \frac{17}{52}

This cannot be simplified further, so the probability is 17 in 52, or 33%.

hope this helps!

MARK AS BRAINLEST
WARRIOR [948]

Answer:

{- 2, - 4, - 6, - 8, - 10 }

Step-by-step explanation:

Given

f(x) = 2x - 6 with domain { - 2, - 1, 0, 1, 2 }

To obtain the range substitute the values of x from the domain into f(x)

f(- 2) = 2(- 2) - 6 = - 4 - 6 = - 10

f(- 1) = 2(- 1) - 6 = - 2 - 6 = - 8

f(0) = 2(0) - 6 = 0 - 6 = - 6

f(1) = 2(1) - 6 = 2 - 6 = - 4

f(2) = 2(2) - 6 = 4 - 6 = - 2

Range is { - 2, - 4, - 6, - 8, - 10 }
