Question

If you flip two coins 68 times, what is the best prediction possible for the number of times both coins will land on heads? times

Answer 1

Given : flip two coins 68 times

To find : what is the best prediction possible for the number of times both coins will land on head

Solution:

if we flip two coins  

then sample space = { HH , HT , TH , TT }

n(S) = 4

Both coins land on heads = { HH }

n( E) = 1

Probability that both coins land  on Heads  = 1/4

Coin flipped 68 times

best prediction possible for the number of times both coins will land on heads  =  (1/4) * 68  = 17

17 times is the best prediction possible for the number of times both coins will land on heads
