Question

When 2 coins are tossed simuntanously what is the probability of getting at most 1 head.

Answer 1

The favorable outcome of getting at most 1 head = (HT, TH, TT).

The probability of getting atmost 1 head = 3/4.

Hope this helps!

Answer 2

probabilities or possibilities -
one coin has only 2 sides- heads/tails
          
coin 1 -h                          coin 2 -h
coin 1 -h                          coin 2 -t
coin 1 -t                          coin 2 -h
coin 1 -t                          coin 2 -t

total no. of outcomes = 4
no. of tosses with a head =3
probability =  favored outcomes/ total outcomes
=4/3
