A deck of 52 cards contains 12 picture cards. If the 52 cards are distributed in a random manner among four players in such a wa
Mkey [24]

Answer:

The probability that each player will receive three picture cards = 0.0324

Step-by-step explanation:

As given,

A deck of 52 cards contains 12 picture cards

Remaining card = 52 - 12 = 40

So,

Total number of ways in which 12 picture card is distributed = \frac{12!}{3! 3! 3! 3!}

Now,

The Total number of ways in which Remaining cards are distributed = \frac{40!}{10! 10! 10! 10!}

So,

Total number of ways of getting 3 picture card and remaining card = \frac{12!}{3! 3! 3! 3!}× \frac{40!}{10! 10! 10! 10!}

= \frac{12! 40!}{(3!)^{4} (10!)^{4}  }

Now,

Total number of ways to distribute 52 cards so that each people get 13 card = \frac{52!}{13! 13! 13! 13!} = \frac{52!}{ (13!)^{4} }

∴ The probability = \frac{\frac{12! 40!}{(3!)^{4} (10!)^{4}  }}{\frac{52!}{(13!)^{4} }}

                            = \frac{12! 40!}{(3!)^{4} (10!)^{4}  }×\frac{(13!)^{4} }{ 52! }

                           = \frac{12! 40!}{(3!)^{4} (10!)^{4}  }×\frac{(13.12.11.10!)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41.40! }

                           = \frac{12!}{(3!)^{4}   }×\frac{(13.12.11)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}

                           = \frac{479,001,600}{(6)^{4}   }×\frac{(1716)^{4} }{ 52.51.50.49.48.47.46.45.44.43.42.41}

                           = 0.0324

∴ we get

The probability that each player will receive three picture cards = 0.0324

Lily recieves 30 messages on her cell phone.Of those messages,1 over 5 are picture messages and 7 over 8 of the remainder are te
lesantik [10]
So we are starting out with 30 messages.

If 1/5 of the messages Lily receives are picture messages, then take 1/5 x 30 to find out how many that is.

1/5 x 30 = 30/5 = 6. So Lily receives 6 picture messages. 

If 7/8 of the remaining messages are texts, then we need to find the number of remaining messages. If 6 are pictures and she receives 30 overall, then 30 - 6 = 24, the remaining number of messages. Since we know 7/8 of <em>this </em>number is the number of texts Lily received, let's do some more multiplication:

7/8 x 24 = (7 x 24)/8 = 168/8 = 21.

So Lily received 21 text messages, 6 picture messages, and 3 of something else!

You will not invited

Mean is best measure of average.

Given:

Class rank is at least = 90th percentile

Rank 30 out of 128 student  

Find:

1. Invited for membership or not

2. Best measure of average

Computation:

Rank in total = [(100 - Percentile)(Total students)]/100  

30 = [(100 - Percentile)(128)]/100

3000 = [(100 - Percentile)(128)]

23.4375 = 100 - Percentile

Percentile = 100 - 23.4375

Percentile = 76.5625  

Since Percentile smaller than 90, So, you will not invited to membership

Mean is best measure of average.
