a.
9
b.
7
c.
13
d.
8


Solution:

The spinner is NOT divided into 2 equal regions. The pink region is more than the green region. So, the spinner is more likely to stop on pink than green.

Jeff spinned the spinner 20 times.

Out of 20 spins, 13 times the spinner stopped on pink color.

So, the remaining ( 20 - 13) = 7 times, the spinner stopped on green color.

So, 7 tally marks should come against the green color.
