What are the odds against choosing a blue marble from a bag that contains two blue marbles, one green marble, seven white marbles, and four red marbles?

12: 2

2: 14

14: 2

10: 2

Odd against will be 12 : 2

So option (a) will be correct option        

Step-by-step explanation:

We have given that a bag contain two blue marbles, one green marble, seven white marbles and four red marbles

So total number of marbles = 2+1+7+4 = 14 marbles

We have to choose blue marbles

We know that

The odds against - the ratio of the number of ways that an outcome cannot occur compared to in how many ways it can occur.

So

Odds against = Number of failures: Number of successes

Number of failures = 14 -2 =12

So odd against = 12 : 2

So option (a) will be correct option

see below

step-by-step explanation:

7.   there are 10 data points in the set.   the middle point is between 5 and 6.   the middle point in the top half is 8   and the middle point in the bottom half is 3. to find the iqr , take point 8 and subtract point 3

mid term   point 8 = 100   point 3 = 88

iqr = 100-88 = 12

final   point 8 = 93   point 3 = 78

iqr = 93 - 78 = 15

the final has the greatest iqr

6.   b - there is a high data value that causes the data set to be asymmetrical for the males: the data for males are high and asymmetrical .   there is an outlier for the males that skews the data

5.   the   iqr is a better measure of spread for the movies and basketball games.   since the basketball game has an outlier, we do not want to use standard deviation for measurement.  

3.   the exam median is much higher than the class median.   the median line is farther to the right on the exams

2.   there is no way to tell what the means are from the box and whisker plots.
