Answer:
Step-by-step explanation:
If it is a fair coin, he should expect heads about 1/2 the time.
1/2 of 30 = 15
He should expect 15 heads.
You can solve this with a proportion. If you know that 23 tagged alligators were in a 200 alligator sample, there are 90 tagged alligators in the entire river. Written otherwise:
23/200 = 90/x
and solve for x:
x = 782.608...
So the "best estimate" would be around 783 alligators. Hope that helps! If you liked this answer please rate it as brainliest!! thank you!!!
