a cookie jar contains 3 vanilla, 2 chocolate chip, and 7 gingersnap cookies. Of one cookie is taken at random from the jar, what is the probability that it will be a vanilla cookie?
Total cookies = 3 + 2 + 7
Total cookies = 12
P(Vanilla) = Vanilla Cookies / Total Cookies
P(Vanilla) = 3/12
Simplified dividing top and bottom by 3, we have:
P(Vanilla) = 1/4
Total cookies = 3 + 2 + 7
Total cookies = 12
P(Vanilla) = Vanilla Cookies / Total Cookies
P(Vanilla) = 3/12
Simplified dividing top and bottom by 3, we have:
P(Vanilla) = 1/4
