Suppose x coins are tossed. write an expression to represent the number of possible outcomes.

Step-by-step explanation:

One coin tossed:

Total outcomes = {H,T} =2

Two coins tossed:

Total outcomes :{HH,HT,TH,TT} = 4

Three coins are tossed:

Total outcomes : {HHH,HHT, HTT,TTT,THH,TTH,THT,HTH} =8  

So, 1 coin tossed

      2 coins tossed

      3 coins tossed

Continuing in this manner ..

      x coins tossed

Thus an expression to represent the number of possible outcomes when x coins are tossed :
