Introduction to Probability Review

The spinner shown is divided into 6 equal parts. Suppose you were to spin the spinner 72 times. Predict the number of times you would land on an odd number.

Tessa flipped a coin two times during a probability experiment. The outcomes of the first 50 trials are shown in the table. Based on the results, in how many of the next 150 trials will the outcome be exactly 2 coins showing yellow?
