5. A bag contains 20 red tickets and 12 blue tickets. What is the probability of randomly selecting a blue ticket from the bag?
OA.3/11
O B.4/5
O c.3/8
OD.1/2

c,3/8

Step-by-step explanation:

total number of tickets=20+12=32

P(blue ticket is selected)=12/32=3/8

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
