A coin is tossed three times in succession. If `E`is theevent that there are at least two heads and `F`is theevent in which first throw is a head, then find `P(E//F)dot` |
Answer» Correct Answer - `3//4` `P(E)=4/8=1/2{because"favorable cases are"THH, HTH, HHT, HHH]` `P(F)=4/8=1/2[because"favorable cases are"HTH, HHT,HT T, HHH]` `P(EnnF)=3/8` `P(E//F)=(P(EnnF))/(P(F))=(3//8)/(1//2)=3/4` |
