Answer:
0.18173219.
Step-by-step explanation:
We have been asked to find what will be the probability that at least 6 of 9 adults use their smartphones in meetings or classes.
We will find our answer using Bernoulli's trails.
First of all we will find the probabilities when r is 6, 7,8 and 9 then we will add them all.
When r=6,
Similarly we will find Probabilities when r=7, 8 and 9.
When r=7
When r=8
When r=9,
Now let us add all the probabilities to get the final answer.
Therefore, probability that at least 6 of 9 adults use their smartphones in meetings or classes is 0.18173219.
