To solve:
Simplify 128x^5/8x first
16x^4
then divide by 1/4
16x^4•4/1=64x^4
Answer: 64x^4
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.
