Answer: C. 180 times
Step-by-step explanation:
From the 60 trials, the percentage of times Laura picked a green marble was:
= 100% - Percentage of times blue and red were picked
= 100% - 25% - 15%
= 60%
If these results were repeated with 300 trials, the number of times Laura would be expected to pick green would be:
= 60% * 300
= 180 times
Answer:
The answer is for this question is 5.
Answer:
B. Write each student's name on a slip of paper and put the slips in a bag. Randomly draw a slip of paper. The student whose name is on the paper wins
30/80 = 0.375(100) = 37.5%
30 is 37.5% of 80
You would have a 26% chance. If you cross multiply using 15/100 and 40/x. 100 times 40 then divide by 15.
