Question

if three coins are tossed then what is the probability of getting 2 head

Answer 1

your answer is 3/8.....the possible outcomes are (H,H,H) (H,T,H) (H,H,T) (T,H,H) (H,T,T) (T,H,T) (T,T,H) and(T,T,T) are 8 in this outcomes with two heads is 3....so,probability is3/8..

Answer 2

total no.of outcomes=4
getting head 2times
so,
HHH,HTH,TTT,THT
p(e)= total no.of outcomes/favorable outcomes
then,4/2
2 is the answer
