What is the probability of picking either a pair of white socks or a pair of black socks?

What is the probability of picking either a pair of white socks or a pair of black socks?

So, the probability of picking a matching pair of black socks is 1/2 of 11/23. The probability of picking a pair of white socks is also 1/2 of 11/23, meaning in order to get the probability of picking any matching pair, you add these two together.

What is the probability that both socks are black?

What is the probability that both socks are black? – Quora. Kinda easy … first sock has a 6/14 chance of being black, and if it is black, the second has a 5/13 chance … multiplying them together you get 30/182 or 15/91, which is about 16.5%.

What is the probability of getting two socks the same color?

Picking the first sock of the two with the same color has the probability of 2/6, and therefore picking the second sock with the same color has a probability of (2−1)/(6−1)=1/5 respectively.

How many socks is a 6 pair?

12 socks, 6 pairs!

How do you find the probability?

How to calculate probability

1. Determine a single event with a single outcome.
2. Identify the total number of outcomes that can occur.
3. Divide the number of events by the number of possible outcomes.

What is the probability of an event that is certain?

1
Answer: The probability of an event that is certain to occur is 1. Let’s look into an example to understand this. Explanation: An event whose occurrence is 100% sure, those events are called certain events.

What is a six pack of socks?

Socks are generally counted and sold in pairs. A six pack refers to six pairs.

How do you find the probability of a sample mean?

Suppose we draw a sample of size n=16 from this population and want to know how likely we are to see a sample average greater than 22, that is P( > 22)? So the probability that the sample mean will be >22 is the probability that Z is > 1.6 We use the Z table to determine this: P( > 22) = P(Z > 1.6) = 0.0548.

What’s the probability of picking black or white socks?

There are 6 pairs of black socks and 6 pairs of white socks.What is the probability to pick a pair of black or white socks when 2 socks are selected randomly in darkness. This question was asked in Aamaon. Probability of picking any 2 same color socks = P1+P2 = 66/276 + 66/276 = 11/23 hey selecting a white/black socks z 1/2 ri8 (12/24).

Are there 7 white socks and 4 black socks?

Originally Answered: There are 7 white socks and 4 black socks in a draw. What is the probability that 2 socks are the same colour if pulled out at random?

How many pairs of socks are the same color?

You just pick the first sock (without caring which one or which color it is). There are 23 socks left with 11 of the same color as of the first sock. So there is 11/23 chance to make a pair. No need to analyze black or white separately. Nobody has asked if these socks are already paired? Surely nobody puts single socks away…

How many white socks are in a drawer?

You can select 2 of the 11 socks in the drawer in 11 x 10 / 2 = 55 ways. You can select 2 of the 7 white socks in 7 x 6 / 2 = 21 ways. You can select 2 of the 4 black socks in 4 x 3 / 2 = 6 ways.
