A spinner is divided into 4 sections. The spinner is spun 100 times.
The probability distribution shows the results.
What is P(1≤x≤3)?
Enter your answer, as a decimal, in the box.
Presumably the spinner is fair so that the probability of landing on 1-4 are all 1/4
In this case P[1<=x<=3] = P+P+P = 3/4
