Question

PLEASE HELP 70 POINTS

4a. An experiment had the following result for 20 flips of a coin: P(Tails) 12/20 P(Heads) = 8/20. If you flip 90 more times, how many would be tails?

4b. Explain how many flips would be tails if you flip 100 more times.

Answer 1

4a. About 54 times NOT INCLUDING THE FIRST TRIAL

4b. About 60 times NOT INCLUDING THE FIRST TRIAL

Explanation:

I say about because we don't know if it's ALWAYS going to be the same results.

4a. Also 12*4 because it's 20 times so 20*4=80 then you add half of it to become 90 and you get 54

4b. 12*5 because 100/5=20 for the 20 trials of them
