Question

a die was rolled 30 times. it landed on four, 7 times. what was the experimental probability for landing on a four? $\frac{7}{30}$ $\frac{1}{4}$ $\frac{1}{6}$

Explanation:

Step1: Recall experimental - probability formula

Experimental probability \(P(E)=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\)

Step2: Identify values

The number of favorable outcomes (landing on four) is 7, and the total number of outcomes (number of die - rolls) is 30.

Step3: Calculate probability

\(P=\frac{7}{30}\)

Answer:

\(\frac{7}{30}\)
