Step-by-step explanation:

Hope this helps you.
Let me know if you have any other questions :-):-)
#3. the probability of spinning "rock" is 25% or 1/4 so we can use this probability to predict the number of times we would expect to get "rock" in 80 spins as follows:
25% of 80 = .25(80) = 20 So how likely is it we spin 20 'rock' out of 80 spins? At 25%, not very likely..
#4.
A. True
B. True
C. False, the theoretical probability of make make using the spinner is

or about 56%
No you would not have enough flour because if you add those to mixed numbers together you would get 4 and 1/12
