Question

Michelle's class is handing out balloon arrangement consisting of 4 balloons each each balloon has and equally likely chance of of being red blue or yellow Michelle created a spinner to simulate this probability here is Michelle's data from 30 trials of 4 spins on the spinner (r = red, b = blue, y = yellow)

ybrr bybb rbbb rrry rbbb rryy yybb ryry ryyr rbyr ryyr rryy rrrr yrby bbyy byyr byyr byyb rbby ybry rryy rbrr rybb bbbr rrbr ybry ryrr rryb rrrb rryr

According to this data what is the experimental probability that an arrangement will consist entirely of balloons that are the same color?

Answer 1

The answer is 1/30 or 0.0333333...

Explanation:

The way to find experimental probability is by comparing the number of times the event occurs to the total number of trials. In this question, there has only been one arrangement that consists of ballooons that are all the same color. This means that 1 (the number of times the event occurred)/ 30 (total number of trials) is the answer. I hope you have a great day!!
