Answer: 0.951%
Explanation:
Note that in the problem, the scenario is either the adult is using or not using smartphones. So, we have a yes or no scenario involved with the random variable, which is the number of adults using smartphones. Thus, the number of adults using smartphones follows the binomial distribution.
Let x be the number of adults using smartphones and n be the number of randomly selected adults. In Binomial distribution, the probability that there are k adults using smartphones is given by
Where p = probability that an adult is using smartphones = 54% (since 54% of adults are using smartphones).
Since n = 12 and k = 3, the probability that fewer than 3 are using smartphones is given by
Therefore, the probability that there are fewer than 3 adults are using smartphone is 0.00951 or 0.951%.

Answer:
Step-by-step explanation:
-Probability is the likelihood of an event occurring.
-The total number of events is:
-The total number of blue events is:
#Probability of a blue is thus calculated as:
Hence, the probability of choosing a blue marble at random is 37.5%
