Question

If you flip two coins 4 times, what is the best prediction possible for the number of times both coins will land on heads?

Answer 1

heyy dear ur answer...

I read the question as:flip 2 coinsflip 2 coinsflip 2 coinsflip 2 coinsand after doing that how many times did both coins land tails.Assuming fair coins and flips there are 4 outcomes for each time you flip 2 coinshh, ht, th, tt   with the middle being identical assuming coins are identicalso probability of -  hh is 1/4,  ht is 2/4,  tt is 1/4so 25% chance of tt each timeso do it 4 times and the Expected Outcome is that 1 time you will get two tails25% chance out of 4 flips = 1

hope this will help u...............@kundan

Answer 2

Given: two coins are flipped four times.

To find: number of times both will land on heads.

Step-by-step explanation:

Step 1 of 1

When two coins are flipped the total possible outcomes are:

S = {HH, HT, TH, TT}.

Total outcomes, n(S)=4.

Only one times both the coins show HH, so the favourable outcomes are 1.

P(both coins will land on heads)=

$=\frac{favourable-outcomes}{total-outcomes}\\=\frac{1}{4} \\=0.25$

The best possible prediction is 0.25.
