If two coins are tossed simultaneously find the probability of getting 2heads |
|
Answer» 1 by 4 When two different coins are tossed randomly, the sample space is given byS = {HH, HT, TH, TT}Therefore, n(S) = 4.Getting two heads:Let E1 = event of getting 2 heads. Then,E1 = {HH} and, therefore, n(E1) = 1.Therefore, P(getting 2 heads) = P(E1) = n(E1)/n(S) = 1/4. 3/4 |
