Question

If you flip two coins 76 times, what is the best prediction possible for the number of times both coins will land on tails? ​

Answer 1

Explanation:

19

Answer 2

38 times

Explanation:

A coin has two sides, so there is a 50% chance it will land on either side (assuming perfect conditions and that the coin cannot land vertically). With that in mind, if you flip a coin 76 times, 50% or 1/2 of the times the coin should land on tails. That is 36 times. (Once again, this is under perfect testing conditions. In real life, you probably wouldn't get an even split after only 76 flips.)

Hope this helps :)
