<u>  2   </u>  =  <u>  3     </u>

girls = 30 / 2

girls = 15

A stem-and-leaf plot for the number of homeruns hit by 30 high school teams is shown. find the probability that a team chosen at
pantera1 [17]
To answer this you need to read the stem and leaf lot and determine how many values were over 28., Or how many were less than or at 28 and subtract it from 30.

There are 10 teams at 28 or less, so 20 teams are above 28.

The number to the left of the | tells us the tens place of the set of number that come after it.

For example 2|4 7 8 stands for 24, 27, and 28.

If 20 out of 30 were above 28 homeruns, then your probability is 20/30 or 2/3 or 0.667.
