#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%
It would probably depend on what you mean by "smallest". If it means "smallest in magnitude", then of course the smallest slope you can have is zero.
Answer:
Rational
Step-by-step explanation:
Its rational because it has the same numbers/pattern
