Question

A. 12,500
B. 37,500
C. 3,750
D. 50,000

Answer 1

C

Answer 2

150,000?

Answer 3

3coins(50,000times per coin)?

Answer 4

hold on i've calculated how many times 3 heads would appear on each toss.
is that whats required???

Answer 5

You are flipping 3 coins at the same time, and you are doing this 100000 times. So you could get things like:

HHH
TTH
THT
etc.

The question is how many times do you expect exactly one heads to show up. So you want

TTH
THT
HTT

Answer 6

possible configurations with one head upward:3
total possible configurations of the three coins=2^3=8
so each toss has a 3/8 chance of puling up one heads
right guys? (I'm not the best with probability0

Answer 7

There are 8 possible ways for the coins to turn up (2 for each coin, so 2^3 = 8), and three of those possibilities have exactly one head. So the probability is 3/8. 3/8 of 100000 is 37500. I think this is the correct way to interpret the problem.
