Answer:
There is a 42/55 or 76.36% chance that Shaina will not pick a sugar cookie
Step-by-step explanation:
13 sugar, 16 chocolate chip, 12 oatmeal, and 14 peanut butter
Total amount besides sugar cookies = 16 + 12 + 14 = 42
42 besides sugar / 55 total = 42/55
There is a 42/55 chance that Shaina will not pic a sugar cookie
42/55 = x/100
Cross Multiply
4200 = 55x
x = 76.36
76.36%
There is a 42/55 or 76.36% chance that Shaina will not pick a sugar cookie from the tray
Hope this helps :)
