Answer:
A
Step-by-step explanation:
Given table:
color ----- Frequency
Red ------ 14
Green ----- 19
Blue -------- 21
Yellow ----- 16
Number of process repeated (trials) = 70 times
Probability (event) = number of times the event occurs / total number of trials
From the table we can see that the number of times she pick the blue marble is 21
Probability of picking a blue marble on next try =
= ![\frac{3}{10}](https://tex.z-dn.net/?f=%20%5Cfrac%7B3%7D%7B10%7D%20%20)
Standard for of 300,000+40,000+60+7 would be 340,067
