Ax - b = c....subtract ax from both sides
-b = -ax + c <==
or it could also have been b = ax - c (but that ones not there)

3 cards are drawn from a standard deck without replacement. What is the probability that at least one of the cards drawn is a re

Rudik [331]

Answer: $\dfrac{15}{17}$

Step-by-step explanation:

Total number of cards in a deck = 52

Number of red cards = 26

Number of cards not red =

Number of ways to draw not red cards = $^{26}C_3$

Total ways to draw 3 cards = $^{52}C_3$

The probability that none of three cards are red = $\dfrac{^{26}C_3}{^{52}C_3}$

$=\dfrac{\dfrac{26!}{3!(26-3)!}}{\dfrac{52!}{3!(52-3)!}}$ [∵ $^nC_r=\dfrac{n!}{r!(n-r)!}$ ]

$=\dfrac{\dfrac{26\times25\times24\times23!}{(23)!}}{\dfrac{52\times51\times50\times49!}{3!(49)!}}=\dfrac{2}{17}$

Now , the probability that at least one of the cards drawn is a red card = 1- Probability that none cards are red

$=1-\dfrac{2}{17}=\dfrac{17-2}{17}=\dfrac{15}{17}$

Hence, the required probability = $\dfrac{15}{17}$

What is the median of the data represented in the line plot?

nevsk [136]

Answer:

The answer is Choice D

Step-by-step explanation

The median is the middle value in the given set of data.

If the data is even, then there will be two middle numbers, then the median is the average of these two middle numbers.

Thus, from the data, it is obvious that the number of data in the given set is 13.

Hence, the middle number is 23.

Therefore, the median of the data is 23.
