According to a survey, 15% of city workers take the bus to work. donatello randomly surveys 10 workers. what is the probability that exactly 6 workers take the bus to work

0.001
0.002
0.128
0.900

0.001

Step-by-step explanation:

Given:

Total number of workers, .

Number of workers taking bus,

Let the probability of taking bus be success and denoted by .

So,

Therefore, probability of not taking bus,

Using Bernoulli's distribution of getting successes out of trials.

∴

Plug in 0.15 for , 0.85 for , 10 for and 6 for

So,  

Therefore, the probability that exactly 6 workers take bus is 0.001.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
