2 coins are tossed at the same time There are 3 colums in a chart(adsbygoogle = window.adsbygoogle || []).push({});

1) Heads-Heads

2) Heads-Tails or Tails-Heads

3)Tails-Tails

the coins were tossed 40 times simultaneously.

What was the probability that heads-tails (or tails-heads) would appear? Show calculations.

(HINT: The probability of these two combinations must be added together because they were recorded together.)

Im thinking its 2/4 but not sure, and dont know what to show as calculations.

PLEASE HELP ME!
